Rockingham foyer blood drops (LAPD Item 12)
Blood stain in the foyer of Simpson's Rockingham home. Multiple drops were collected from the wooden floor as LAPD Item 12; PCR and RFLP DNA analysis matched O.J. Simpson at all five probes with frequencies ranging from 1 in 170 million to 1.2 billion. Defense experts highlighted the sample's high DNA concentration and proximity in processing to victim reference samples as a contamination risk.
