MA v. Karen Read (2024) – Day 19 Trial Summary
Day 19 of the Commonwealth v. Karen Read trial shifted the evidentiary focus heavily toward physical and biological forensics, featuring key members of the Massachusetts State Police (MSP) Special Emergency Response Team (SERT) and crime lab scientists. The prosecution aimed to heavily reinforce its motor-vehicle-impact theory by documenting the methodical grid search that uncovered automotive debris at the scene, alongside the laboratory analysis linking those physical fragments directly to the suspect vehicle’s damaged taillight housing.
However, the defense aggressively used cross-examination to expose structural flaws in the state’s case. They highlighted prolonged gaps in scene security before the specialized search team was even deployed, established that primary investigator Trooper Michael Proctor retained personal custody of the victim’s clothing for months before laboratory submission, and forced forensic scientists to admit that critical pieces required to complete the shattered taillight puzzle were entirely missing.

Connection to the case
O’Hara led the specialized state police search team deployed to 34 Fairview Road on the late afternoon of January 29th, 2022.
Summary Of Testimony
O’Hara testified that his team responded to an operational request at 3:48 PM, arriving at the scene at 4:56 PM to execute an intensive grid search during active blizzard conditions. He detailed uncovering a black Nike sneaker matching the victim’s clothing, alongside multiple fragments of red and clear plastic debris beneath the snow. Under cross-examination, O’Hara conceded he held zero personal awareness that the outdoor crime scene had been left entirely unattended and unsecured by law enforcement for hours prior to his team’s arrival, and admitted he did not know the precise total volume of plastic fragments ultimately processed from the scene.
Key evidence introduced!
- Physical recovery tracking data documenting the location of six to seven pieces of red and clear automotive plastic
- Discovery of the victim’s missing black sneaker.

Connection to the case
A forensic scientist who conducted the initial physical intake processing and microscopic trace examinations of both the suspect’s Lexus SUV and the victim’s recovered clothing items.
Summary Of Testimony
Hartnett testified to her physical evaluations of the Lexus SUV inside a secure garage, documenting an irregularly fractured rear passenger-side taillight housing unit and identifying a deep scratch on the rear bumper. She further noted finding a piece of clear plastic debris lodged on the bumper and tiny, microscopic hair-like fibers attached to the vehicle’s exterior paneling. Under cross-examination, Hartnett acknowledged that she did not perform any biological fluid or DNA swabbing on the bumper scratch, and confirmed that subsequent microscopic processing of the isolated fibers revealed they were entirely synthetic and lacked any human biological roots.
Key evidence introduced!
- Found Hair On Rear bumper of the Lexus SUV.
