Three blood stains designated LAPD Items 115, 116, and 117 were collected from the rear gate at 875 South Bundy Drive on July 3, 1994. PCR testing excluded both victims and did not exclude O.J. Simpson; Item 117 yielded an estimated 150–166 nanograms of DNA and was reported as an eight-probe RFLP match in criminal testimony and a nine-probe match in civil testimony, while counsel disputed the delayed collection, DNA quantity, degradation, EDTA testing, and claimed June 13 observations.
FBI chromatograms of rear-gate stain Q204 included Run No. 4084 (Defense 1260-A / Defendants' 1218) and Run No. 4049 (Defense 1260-B / Defendants' 1219), which Dr. Fredric Rieders presented as positive for EDTA. A third repeat test, Defendants' 2292, was negative, and later testimony disputed whether the testing graphs showed a full or partial daughter spectrum.
A defense chart comparing estimated quantities of high-molecular-weight human DNA in Bundy blood-drop items and rear-gate sample 117. Gary Sims said the displayed figures appeared reasonable, and the chart was later discussed during Dr. John Gerdes’s testimony.
Defense charts comparing DNA concentrations in rear-gate sample 117 with Bundy and Rockingham blood-drop samples. They were displayed to the jury, and witnesses described the mathematics or conclusions as substantially correct.
A chart entitled “Comparison of Swatched DNA Samples to 117,” introduced during Robert Blasier's cross-examination of Gary Sims, comparing DNA quantities from the back-gate stain with Bundy and Rockingham drops.
An annotated electrophoresis-plate printout introduced as People's 224-D and passed to the jury with the Item 117 lane physically cut off pursuant to the court's order.
High-performance liquid chromatography (HPLC) graphs produced by FBI Agent Roger Martz from February 23 testing of gate stain Q204, sock stain Q206, Nicole Brown Simpson reference blood, and O.J. Simpson reference blood (People's 546-A through 546-D). Martz presented these graphs as corroborating his earlier LC-MS/MS findings that no EDTA was detected in the evidence stains.
