Rockingham Interior Blood

26 items · 26 physical · 23 with detail pages

Blood evidence from O.J. Simpson's Rockingham residence—foyer stains (LAPD Item 12) and bathroom samples (Item 14)—subjected to PCR and RFLP DNA analysis, all matching Simpson. Criminalist Dennis Fung collected and testified about these samples. The prosecution relied on internal blood evidence to connect Simpson to the crime; the defense attacked Fung's collection procedures and chain of custody. Photographs, DNA autoradiographs, and crime scene diagrams document this contested forensic battleground.

Defense experts highlighted the sample's high DNA concentration and proximity in processing to victim reference samples as a contamination risk.
