DNA Evidence Overview — Tail Light and Shoe
Jackson's Trial 2 opening claimed absent DNA on plastic shards and unidentified male profiles on the taillight and shoe. These were opening-statement claims, not evidence.
About
Jackson used these claims to challenge the Commonwealth's account: he said no DNA was recovered from plastic shards alleged to have contacted O'Keefe's arm, while a sample from outside the taillight housing contained O'Keefe plus two unidentified male profiles and O'Keefe's shoe sample contained five unidentified male profiles. These were opening-statement claims, not evidence, and this source does not establish the underlying laboratory results or any inference about contact, custody, timing, or identity.
