Killer Or Cover-Up Murder Trial

Maureen Hartnett, the crime scene analyst working this case, got grilled by Karen Read's defense under cross-examination. Hartnett testified that she did not know when the pieces of glass or the hair got on the defendant's SUV. Her lawyers maintained throughout this trial that she was framed by someone who fatally beat John O'Keefe inside a home and that the homeowner's relationship with local and state police tainted this investigation.
