The Illinois State Police Forensic Science Center at Chicago recently received five large, plastic-wrapped bundles of plant material, suspected marijuana. The exhibits were randomly selected from a total of 395 such bundles that had been seized by the Chicago Police from a hidden compartment in a tractor trailer arriving in Chicago from St. Louis. The packaging appeared to be routine, and consistent with similar, previously encountered bundles (see Photo 1). However, upon opening the first bundle, a white powdery substance was found between layers of the plastic wrapping, and as the plastic was folded back to remove the plant material, a liquid substance dripped from the packaging and onto the powder, resulting in an effervescent reaction that produced a gas with a chlorine type odor. The evidence was transferred to a ventilated area for further investigation, where careful dissection revealed the following (outside to inside): Plastic wrap; white powder; plastic wrap; sticky, yellow to brown liquid; plastic wrap; white powder; plastic wrap; plant material (see Photo 2). The liquid had a pH of around 2 (not further identified). Analysis of the powder with FTIR and GC/MS indicated a chlorinated compound (not further identified). Analysis of the plant material (total gross mass (including packaging) approximately two tons) by microscopy and Duquenois-Levine confirmed marijuana. Due to the hazardous nature of the sample, it was immediately destroyed under court order. Investigative intelligence suggested that the shipment originated in Mexico. This was the laboratory’s first encounter with hazardous packaging of this nature.

[Editor’s Notes: The white powder was suspected to be a pool chlorinating compound. It is unknown whether this packaging was intended to harm, or rather was to eliminate odors (thereby reducing the possibility of detection by canines or trained law enforcement personnel).]

The Vermont Forensic Laboratory (Waterbury) recently received nine hexagonally shaped objects (approximately 40 x 10 millimeters), each individually wrapped in plastic and containing on average 4.7 grams of compressed tan powder, suspected heroin (see Photo 3). The exhibits were seized in Montpelier in a joint operation by the Montpelier and Berlin Police Departments. These unusually shaped objects are occasionally referred to as “fingers”. Analysis by GC/MS confirmed heroin (not quantitated, but fairly high purity based on the chromatography and lack of adulterants). Although the laboratory has previously encountered heroin “fingers”, this was the first such submission in many years.

The Kentucky State Police Central Forensic Laboratory (Frankfort) recently received two large ziplock bags, each containing several dozen cylinders of off white, compressed powder, suspected cocaine (see Photo 4). The exhibits were acquired in Shelbyville by the Kentucky State Police (Shelbyville is located west of Frankfort (east of Louisville)). The cylinders measured approximately 3.8 centimeters in length and 1.9 centimeters in diameter (averages), and had an average weight of approximately 10 grams (see Photo 5). Analysis of the powder (total net mass 1,500 grams) by GC MS, GC FID, and IR confirmed cocaine hydrochloride (not quantitated). Investigative intelligence indicated that these cylinders were originally smuggled into the U.S. from Mexico inside C-cell battery casings. This was the first submission of this type to the laboratory.

LSD BLOTTER ACID MIMIC CONTAINING 4-CHLORO-2,5-DIMETHOXY
PHENETHYLAMINE (2C-C) IN WASHINGTON COUNTY, OREGON

The Oregon State Police Portland Metro Laboratory (Clackamas) recently received five small, rectangular pieces of card stock with black print on both sides, apparent LSD “blotter acid” but submitted as an unspecified “controlled substance/chemical”. The exhibit was seized by the Washington County Sheriff’s Office (circumstances unknown; Washington County is in the northwest quadrant of Oregon). The pieces were about 1.6 x 2 centimeters and were further divided into four smaller areas (each about 0.9 x 1 centimeters). Each area had “2C-C” printed on one side and portions of what appeared to be organic synthesis instructions on the reverse (see Photos 6 and 7). 2C-C is an informal abbreviation for 4-chloro-2,5-dimethoxy-phenethylamine, a hallucinogenic phenethylamine. The synthetic instructions were determined to have been taken verbatim from PIHKAL (Phenethylamines I Have Known and Loved, by Shulgin and Shulgin, pps. 509 510). Analysis by UV and GC/MS confirmed 4-chloro-2,5-dimethoxyphenethylamine (2C-C, also commonly named as 2,5-dimethoxy-4-chlorophenethylamine). The identification was based on comparison with the spectrum found in “Tryptamines and other Psychotropic (Mind Altering) Substances” [2004 AAFS Meeting - Workshop #5], and was not verified due to the lack of a reference standard. The sample was not quantitated; however, the concentration was judged to be much greater than typical LSD loadings, based on the chromatography. This is the first known submission of 4-chloro-2,5-dimethoxyphenethylamine to the Oregon State Police.

The DEA North Central Laboratory (Chicago, Illinois) recently received nine square black vinyl cushioned seats and nine rectangular black vinyl back supports (both from weightlifting benches), all containing packages of white powder, suspected cocaine (see Photo 8). The exhibits were seized by U.S. Customs and Border Protection (CBP) personnel at O'Hare International Airport from an individual who had transported them as "excess baggage" on a flight from Morelia, Mexico. The powder was packaged within multiple layers of plastic bags, covered with duct tape, and further concealed within 2 sheets of plywood. Analysis of the powder (total net mass 27.17 kilograms) by color tests, GC, GC/MS, and FTIR confirmed 86 percent cocaine hydrochloride. Further investigation determined that the same individual had transported three sets of these seats and supports to the U.S. on a previous flight.

VARIOUS CONSUMER PRODUCTS CONTAINING MARIJUANA/THC
IN SAN LORENZO, CALIFORNIA

The DEA Western Laboratory (San Francisco, California) recently received several exhibits of apparent consumer products suspected to contain marijuana or THC. The exhibits were seized by Alameda County Sheriff officers and DEA agents from a residence in San Lorenzo, California (San Lorenzo is located approximately 15 miles southeast of Oakland). Many of the exhibits were marked for “medical use”, and so were suspected to be associated with the “medical marijuana” outlets in the Bay Area. The exhibits included plant material, various “medical use” products, a marijuana sifting device, and glass cooking dishes (e.g., see Photos 9 - 12 (other items not shown)). Analysis by GC/MS confirmed the presence of THC in the plant materials, “medical use” products, and residues (quantitations not performed). The Western Laboratory has received similar products in the recent past, but not items that appeared to be commercially produced and labelled (including “nutritional” information).

HEROIN SAMPLES CONTAINING DIMETHYL SULFONE (CHICAGO, ILLINOIS)
AND DILTIAZEM (NEW BRITAIN, CONNECTICUT)


The DEA Special Testing and Research Laboratory (Dulles, Virginia) recently received two unusual heroin exhibits from Chicago, Illinois and New Britain, Connecticut (details of seizures not provided). The first consisted of 2.4 grams of white powder; analysis by GC/FID, GC/MS, and NMR confirmed 21 percent heroin hydrochloride and 11 percent dimethyl sulfone. The second consisted of 0.56 grams of white powder; analysis (same techniques) confirmed 36 percent heroin hydrochloride and 6 percent diltiazem. Dimethyl sulfone is commonly found as an adulterant in methamphetamine, but is rarely encountered in heroin. Similarly, diltiazem has been previously reported as an adulterant in cocaine, but is also rarely encountered in heroin. Signature analysis determined that both samples were of South American origin.

EARLY WARNING - MDMA AND MDA PRODUCERS USING OCOTEA CYMBARUM AS A PRECURSOR

[From the NDIC Narcotics Digest Weekly 2005;4(41):1
Unclassified, Reprinted with Permission.]

Forensic chemists have reported that Ocotea cymbarum has been discovered at several clandestine laboratories in the Northeast. Ocotea cymbarum is an essential oil - distilled from the trunk bark of a tropical tree native to Brazil, Colombia, and Paraguay - that typically contains between 80 and 94 percent safrole, a precursor for MDMA (3,4-methylenedioxymethamphetamine, also known as ecstasy) and MDA (3,4-methylenedioxyamphetamine). Ocotea cymbarum also is known as Brazilian sassafras oil but is sold under other names and spellings such as Ocotea cymbarum oil, Ocotea cynbarnum, Ocotea cymbarium, and “Oil of Ocotea.”

MDMA and MDA producers are using Ocotea cymbarum because the importation and distribution of other precursors and sources of precursors - such as safrole and other essential oils containing safrole, including sassafras oil and camphor oil - have been monitored heavily by law enforcement. In the United States, safrole and essential oils rich in safrole are List I chemicals under the Controlled Substances Act. All distributors must be registered with the Drug Enforcement Administration (DEA). Additionally, it is unlawful for any person to possess or distribute a listed chemical knowing, or having reasonable cause to believe, that the listed chemical will be used to manufacture a controlled substance. Law enforcement advisories regarding safrole and essential oils rich in safrole typically have not yet specified Ocotea cymbarum. Ocotea cymbarum is available via the Internet, including at online auction sites, and through mail order from chemical, aromatherapy, and perfume companies. Some criminal groups and independent manufacturers have illegally diverted Ocotea cymbarum from domestic businesses that import large quantities of the oil for legitimate industrial uses, which include the manufacture of fragrances, flavoring agents, and insecticides. A clandestine MDMA laboratory seized recently in New Jersey contained a 5-gallon drum of Ocotea cymbarum that apparently was obtained from an aromatherapy company in the United States. Using a precursor of this quantity could have yielded an estimated 49,000 to 108,000 tablets containing 120 milligrams of MDMA, depending on the method of manufacture. Ocotea cymbarum is most commonly sold via the Internet in 100-milliliter and 500-milliliter quantities; a 500-milliliter bottle of Ocotea cymbarum sells for $20 to more than $100. An MDMA producer with access to the proper chemicals can use a 500-milliliter quantity of Ocotea cymbarum to produce an estimated 1,300 to 2,800 tablets containing 120 milligrams of MDMA. Law enforcement agencies encountering suspicious sales of Ocotea cymbarum should access DEA's advisory on safrole and essential oils rich in safrole at (see: www.deadiversion.usdoj.gov/chem_prog/advisories/safrole.htm)

LARGEST MDMA LABORATORY SEIZURE IN INDIANA HISTORY

On June 22, 2005, the St. Joseph County Metro Special Operations Unit and members of the DEA Merrillville Resident Office Task Force seized a fully functioning MDMA laboratory and 80 grams of the drug in South Bend. Three Caucasian males were arrested and charged with conspiracy to manufacture and distribute the drug. The laboratory operators leased office space in a former factory building and were operating the laboratory in a 700-square-foot room that was equipped with water, electricity, heat, air conditioning, and drive-in access. One of the suspects, who is cooperating with law enforcement, reported that the three men had manufactured three batches of tablets - in quantities of 6,000, 10,000, and 13,000 - immediately before the seizure. The men had produced 15,000 to 25,000 tablets every 7 to 10 days, the majority of which were sent to Georgia and Texas for distribution; however, a small quantity was sold in the South Bend area. The men began producing blue gelatin capsules containing MDMA in 2004; in March 2005 they acquired a tablet press and manufactured 6,000 to 7,200 gray tablets per hour. Three undercover purchases of MDMA were made prior to the laboratory seizure - 20 capsules in October 2004, 100 capsules in February 2005, and 500 tablets in March 2005. During the last undercover purchase on the day of the laboratory seizure, undercover officers bought 5,000 MDMA tablets for $6 each. Investigators determined that many of the chemicals used at the laboratory had been obtained via the Internet; the men had purchased safrole from suppliers in Canada and other chemicals from suppliers in China.

NDIC Comment: This MDMA laboratory, with a production capacity of 2 to 9 pounds, is the largest laboratory seized in Indiana as of the date of this publication. According to the EPIC National Clandestine Laboratory Seizure System (NCLSS), four MDMA laboratories were seized in Indiana between 2000 and 2005. NDIC National Drug Threat Survey (NDTS) 2003 and 2004 respondents in South Bend reported that MDMA availability was low to moderate. NDTS results also reveal that demand for the drug in northern Indiana, specifically in South Bend, has decreased; however, much of the MDMA produced in the aforementioned laboratory reportedly was transported to areas of higher demand.

VERY LARGE SEIZURE OF MDMA TABLETS
IN CANADIAN COUNTY, OKLAHOMA


The Oklahoma State Bureau of Investigation’s Central Drug Lab (Oklahoma City) recently received a submission of over 200,000 tablets (total net mass 136 pounds), suspected Ecstasy (see Photo 13). The exhibits were seized pursuant to a vehicle stop on Interstate 40 in Canadian County (surrounding Oklahoma City) by Oklahoma Bureau of Narcotics personnel (details not provided in accordance with Microgram policy). The vehicle was allegedly travelling from California to Louisiana. The tablets were packaged in 40 plastic bags, which were further contained inside a rolling suitcase and a duffle bag. Each bag contained approximately 5,042 tablets. The tablets had typical Ecstasy tablet weights and dimensions, were in three colors, and had various logos: There were blue tablets with either a “star”, “Superman”, or “Motorola” logo; green tablets with either a “Mercedes”, “Playboy bunny”, or “Motorola” logo; and light purple tablets with a “smiley face” logo (closeup photos not available). Analysis of selected tablets by GC and GC/MS confirmed 3,4-methylenedioxymethamphetamine (not quantitated). Caffeine and procaine were also identified in some of the tablets. This was the laboratory’s largest submission of Ecstasy tablets in at least 10 years, and may be the largest in laboratory and state history.

The DEA Mid-Atlantic Laboratory (Largo, Maryland) recently received a two-exhibit submission, the first consisting of 29 duct-tape wrapped packages each containing one kilogram of a fine tan powder, suspected heroin (see Photo 14), and the second consisting of 25 duct-tape wrapped packages each containing one kilogram of a white powder, suspected cocaine. The exhibits were originally seized in Quito, Ecuador and were submitted for analysis after a controlled delivery in northern Virginia (further details not available). Analysis of the tan powder by GC, GC/MS, and ATR FTIR confirmed 72 percent heroin hydrochloride. Analysis of the white powder (same techniques) confirmed 72 percent cocaine hydrochloride. This was the largest ever heroin submission to the Mid-Atlantic Laboratory. The exhibits in this case were traced back to the Revolutionary Armed Forces of Colombia (FARC).

Computer Corner

New Examiner Interview Topics

#200

by Michael J. Phelan
DEA Digital Evidence Laboratory

One of the most important infrastructure development tasks of all forensic laboratory management personnel is the selection of new forensic scientists. Digital evidence laboratories have some unique candidate assessment issues because the applicants' educational backgrounds and work experiences can significantly vary. DEA has either directly or indirectly (outsourced through a computer support contractor) hired a number of computer examiners to keep up with the growing demand for digital evidence support. Here is a list of leading interview questions that have been used by DEA to identify qualified candidates:

1. “Tell me about your college computer technology coursework.”
Evaluation of a college degree in “computer technology” can be difficult. There are many relevant degrees, including computer science, information science, computer technology, information systems, information assurance, electrical engineering, computer engineering, and more. It is recommended that the actual course curriculum be discussed. In general, the broader and more technical the courses are, the better prepared the candidate will be to confront both digital evidence hardware and software problems. At a minimum, the candidate should have had coursework involving databases, telecommunications, networking, operating systems, and at least one mainstream programming language.
2. “Tell me about any law enforcement or forensic course related studies you have taken.”
A comprehensive assessment of a college degree (either at the Bachelor or Master's level) should include a review of related majors that may be complementary to computer technology coursework or prior work experience. In particular, a major (or minor) in law enforcement studies or forensic science is desirable. Specific topics of relevance can be, e.g.: Search and seizure law, rules of evidence, expert witness testimony (moot court), or basic forensic science principles (scientific method, Daubert, etc.).
3. “What technical certifications have you achieved during the past three years?”
There are a large number and variety of technical certifications that information technology professionals can earn. Digital evidence software vendors may also provide certification(s) in the use of their product(s). Certifications in themselves are an indicator of professionalism. It is best to inquire during the interview how many of the candidate's certifications were granted (or renewed) during the past three years. It is also good to ask what level of effort it took to qualify for certification. Outdated certifications mean very little in the fast world of digital technology.
4. “Tell me about your recent IT work experiences. What has been the most complex problem that you
have solved over the past year?"
Evaluation of prior IT work experience is always a complex task. Many IT jobs (such as system administration, computer help desk support, and computer staging) are highly structured and narrowly focused. Similarly, programming jobs may be highly detailed but lack broad exposure to computer hardware. Each individual's prior work experience should be critically considered to determine if the candidate can successfully handle non routine software and hardware issues.
5. “What experience do you have working as a Team member or Team Leader?”
Can the candidate effectively work in a group environment? It is the nature of the IT field that many of its practitioners are somewhat introverted, and it is important that each individual understand that they are part of a team that provides forensic support both in the laboratory and possibly on site in field settings. How well an individual will function as a team member or team leader can be determined by asking if they have ever worked in a small group environment. Have the candidate discuss what was accomplished by this group. What were the group's strengths and weaknesses? Lastly, what was the candidate's role in the group?

6. “Why are you interested in working at this laboratory?”

Often, the most motivated employees are the best employees. Hiring interviews should include questions regarding motivation for seeking employment at the laboratory. A candidate should be able to articulate a well organized statement on why he/she wants the position. Displaying some knowledge regarding your organization's mission (or at least the broader discipline of digital evidence) should be viewed in a positive light.

7. “What kind of digital evidence examinations are you familiar with? How many cases did you
complete (as the principal examiner) in the last three years? How many exhibits did you examine in that period? Have you ever testified as an “expert witness” in a digital evidence matter?”

Candidates that claim to have prior subject matter training and work experience should be asked to provide a summary of both, along with a list of their recent accomplishments. There is no substitute for recent substantive digital evidence examination work experience. This information is also useful in determining if the candidate's prior work experience involved criminal or civil law enforcement, or administrative or corporate security. Some work backgrounds may be more suitable than others because of the emphasis on chain of custody, and potential public scrutiny of the work product.

8. Please define the following digital evidence examination terms: “Digital evidence”, “computer
forensics”, “image file”, “meta data”, “partition slack”, “logical level data”, “erased file”, “unallocated cluster”, “steganography”, “encryption”, “privileged information”, “Daubert”, “Rule 6(e)”, and “discovery”.

The interview should also attempt to document the breadth of knowledge of a current or recent digital evidence examiner practitioner. Asking for short definitions on a number of topics often can identify candidates that are the best trained or most experienced.
