There are some self-inflicted wounds by investigators in the case," says a former federal prosecutor who watched opening statements on Tuesday for Karen Read's retrial.

Jackson started his opening arguments by saying John O'Keefe did not die from being hit by a vehicle and that lack of integrity in the case stems from now-fired State Trooper Michael Proctor, calling him a "cancer" who fabricated and planted evidence.

The prosecution and defense offered vastly different facts and theories as Karen Read's second murder trial got underway Tuesday.
