b. Senior Criminalist, March 21, 2012 – present: Successfully completed gunshot residue training in September 2012 then began analysis of cases for gunshot residue analysis. Began explosives training and competency testing 2013.
2. Senior Forensic Scientist, Orange County Sheriff-Coroner/OC Crime Lab, May 2008 – March 10, 2011, Controlled Substances: I performed the duties of supervisor of the controlled substances section. My responsibilities included leadership, writing personnel evaluations, time and assignment scheduling, maintaining morale, coordinating court testimony, monitoring court testimony per accreditation requirements, monitoring productivity and quality of the section and individuals, and with the assistance of my team, reduced a backlog of 1100 cases to less than 300 in four months and maintained the low backlog for approximately one-year. Additional duties included updating the quality system manual to meet accreditation standards; recommended budgets for training and vendor contracts; evaluating, purchasing, and validating new instrumentation; coordinated a furniture build-out in the laboratory, purchasing consumable laboratory supplies and materials, acquiring designer and scheduled drug standards, completing management assigned tasks, and other related duties. With a forensic intern and a forensic scientist, developed a new method for the gas chromatography-mass spectrometer to analyze a general unknowns to state an evidential exhibit has no controlled substances detected.
August 2007 – February 2008, Forensic Alcohol & Toxicology (AM&PM)
March 2006 – May 2008, Toxicology (AM&PM)
Performing duties of supervisor of the toxicology section and when the forensic alcohol section supervisor resigned, supervised both sections for five months with a total of 24 personnel. My responsibilities included leadership, maintaining morale, writing personnel evaluations, time and assignment scheduling, coordinating court testimony, monitoring court testimony per accreditation requirements, insuring breath instrument repair, monitoring productivity and quality in both sections, upgrading toxicology to ASCLD-LAB International standards as well as editing and updating the quality system manual, aligning the forensic alcohol section manual to section standards, recommending budgets for training and vendor contracts, evaluating, purchasing, and validating new instrumentation, purchasing consumable laboratory supplies and materials, completing management assigned tasks, and other related duties.
3. Criminalist, Senior Criminalist, Forensic Scientist III, (July 1980 – March 2006), Acting Senior Forensic Scientist (May 1995 - August 1996, 15 months), Orange County Sheriff-Coroner/OC Crime Lab: At the bench level, my assignments include forensic alcohol program (blood, urine, and breath), controlled substances/drugs of abuse analysis section, trace evidence section including paint comparison, glass comparison, mineral identification, determination of hair for DNA analysis, completion of hair comparison training, analysis of many types of unusual trace evidence, explosives analysis, lachrymator analysis, collection and analysis of fire debris for ignitable liquids, and briefly in ante-mortem toxicology. I have been involved in the collection, analysis, and interpretation of evidence from autopsy, vehicle examination, and crime scene (death investigation including fire and post-blast bombing).
For nearly eleven years (February 1989 to 2001) I was responsible for the County fixed and controlled asset (capital assets) laboratory inventory audits converting a manual system to a computerized location system. I provided cost estimates and recommendations to the supervisor for purchasing instruments including gas chromatographs, comparison light microscope, polarized light microscopes, a variety of other microscopes, infrared spectroscopy instrumentation, accessories, and spectral libraries, photographic and photomicrographic equipment, a glass refractive index measuring (GRIM) system, and other trace evidence section equipment, supplies, chemicals, and accessories were part of my duties.
I provided leadership and was technical leader for the trace evidence section beginning in early 1994, then promoted to Acting Senior Forensic Scientist (Supervisor) of the trace evidence and questioned document sections from May 1995 - August 1996. From January to August of 1996, the Evidence Control Unit was also under my supervision. As a Forensic Scientist III and as Acting Senior Forensic Scientist of the trace evidence section, I wrote or supervised the writing of methods, procedures, and training manuals in various areas of trace evidence analysis, personally trained or supervised the training of forensic scientists, proposed capital asset purchases, performed case work on complicated or high profile trace evidence cases, and requested purchase of standards and consumable items. Additionally, as supervisor, I wrote and provided personnel evaluations, completed manager directed projects, managed contracts for instrument maintenance, and dealt with employee/personnel problems, work and time off schedules. Because of insufficient staffing and a county bankruptcy, I coordinated trace evidence personnel assignments with supervisors of the crime scene investigation, forensic alcohol, and controlled substance analysis units to maximize analysts’ time to cover laboratory needs. In August of 1996, I was reassigned to casework duties while retaining a leadership role in the trace evidence section. I have been involved in quality assurance audits for laboratory accreditation. For nearly 25 years I directed and supervised student interns in various projects for several areas of the laboratory.
I trained police officers and phlebotomist technicians to be certified operators for the 4011A and 5000 series Intoxilyzer®. I taught other criminalists instrumental analysis and microscopical methods of evidence characterization and identification to forensic scientists both in-house as well as from other laboratories including the analytical approaches to a variety of unusual trace evidence.
I am familiar with and can use stereomicroscopes (SLM), polarized light microscopes (PLM), scanning electron microscopes with energy dispersive x-ray detector (SEM-EDX), gas chromatographs with flame ionization detector (GC-FID), with mass spectrometry detectors (GC-MS), Fourier Transform Infrared Spectroscopy (FTIR) bench and with attenuated total reflectance (ATR-FTIR), FTIR microscope, the UV-VIS micro-spectrophotometer, ultra-violet spectroscopy, hot stage microscopy, chemical microscopy, chemical color tests, thin layer chromatography (TLC), and X-ray fluorescence spectroscopy.
I have qualified as an expert in over one hundred thirty cases in two states. My testimony includes areas of blood, urine, and breath alcohol analysis, interpretation of blood alcohol levels relating to driving-under-the-influence, drug analysis, fire debris analysis, homicide scene and autopsy evidence collection, explosives analysis, and miscellaneous trace evidence cases.
- Established an outline for an in-house course on Aspects of Courtroom Testimony for new criminalists and assisted in teaching the early classes
- Wrote the practical exercises and assisted in teaching the in-house class on microscopy/polarized light microscopy
- Developed a training course and handouts for the laboratory to help train new deputy district attorneys to learn the capabilities and limitations of forensic alcohol, controlled substances, and toxicology sections.
- Organized and computerized the laboratory fixed and controlled asset lists which reduced audit time to one-and-a-half days from more than a week
- Originated the drug analysis case note worksheets used by Controlled Substances analysts
- Developed an FTIR library of inorganic chemical, and explosives standards
- During construction of the laboratory, designed the Trace section floor plan and work bays in the trace evidence lab
- Created an ignitable liquids database with two other analysts that includes approximately 400 samples. Collectively this database and a software program created by one of the analysts was to be distributed by Agilent Technologies
- Created a smokeless powder database for brand characterization
- Completed a project with the help of interns and toxicologists to compile a decade of post mortem (PM) case data to help in quantitating tissue samples and interpreting PM drug levels.
4. 1979 - 1980. Student Aide, San Mateo County Sheriff Crime Laboratory. Duties included drug analysis, paint comparison and analysis, arson analysis, firearms work up, firearm and toolmark comparison under criminalist supervision, cataloging a firearm reference collection, and other duties as assigned.
