Roger Martz was a participant or observer in the following events:
Four FBI workers who evaluated evidence surrounding the Oklahoma City bombings (see 8:35 a.m. - 9:02 a.m. April 19, 1995 and August 10, 1995) are transferred after a Justice Department report criticizes the FBI’s crime lab procedures. One of those suspended is forensic scientist Frederic Whitehurst, whose long-standing complaints triggered the Justice Department investigation. That investigation found that evidence in about two dozen cases had been mishandled. Whitehurst is placed on administrative leave with pay just days after the report is received by FBI HQ. The Justice Department report does not allege that evidence had been manipulated to benefit prosecutors. Some evidence was possibly contaminated, and in some instances, the FBI laboratory exercised lax control over evidence. Three of the 23 units in the laboratory were found to have substandard procedures. [Washington Post, 1/28/1997; Indianapolis Star, 2003] According to a technician (not Whitehurst), the black denim jeans that accused Oklahoma City bomber Timothy McVeigh (see 8:35 a.m. - 9:02 a.m. April 19, 1995 and August 10, 1995) wore on the day of the bombing were shipped to the forensics lab in a brown paper bag, and not a sealed plastic evidence bag as procedure dictates. A gun and a knife purportedly taken from McVeigh during his arrest (see 9:03 a.m. -- 10:17 a.m. April 19, 1995) were sent to the lab in a manila envelope. According to an FBI summary of interviews conducted with lab technicians, an employee in the explosives unit, LaToya Gadson, told investigators that “the evidence was a ‘mess’ when it came in because it had not been collected in an ‘orderly fashion.’ Additionally, most of the debris was not properly bagged, some was not bagged at all, and many of the bags were not closed tightly, allowing debris to fall out.” Travel cases potentially contaminated with explosive residue from the bomb were placed in an area where bomb debris had been stored awaiting testing, rendering the cases impossible to accurately test. And a technician obtained a false reading of cocaine in McVeigh’s car, possibly from using improperly cleaned equipment. The sample was discarded, a worker says. Three technicians who examined evidence from the bombing case were reassigned: David Williams, who supervised evidence collection; Roger Martz, head of the laboratory’s chemistry unit; and James T. Thurman, chief of the laboratory’s explosives unit. Lab workers say Williams changed his dictated reports in violation of laboratory policy. Martz examined explosive evidence even though he lacked the proper training to do so. [New York Times, 1/31/1997]
