Karen Read pleaded not guilty to murder charges in the death of Boston police officer John O’Keefe and is facing a retrial after a jury was unable to reach a verdict last year.

The retrial of Karen Read, the Massachusetts woman accused of hitting her police officer boyfriend with her car and leaving him for dead, will resume following an abrupt one-day break in court proceedings.

Video played for jurors in the Karen Read trial shows Brian Higgins at the Canton police station on the night John O'Keefe died, Massachusetts State Police Sgt. Yuri Bukhenik testified.

Defense in Karen Read trial proposes that Boston Police Officer John O'Keefe's death might be linked to a "jealousy"-fueled fight with ATF agent Brian Higgins.

Footage shows 'Turtleboy' blogger Aidan Kearney yelling and gesturing at a surveillance camera in a pizza shop owned by Karen Read trial witnesses.

A panel of appeals judges have vacated, but not reversed, an order finding that the Karen Read trial buffer zone for protesters is valid and constitutional.The appeals court is now sending the case back to district court to revisit the buffer zone to see if the rules can be tailored in a way that allows peaceful protests.

Karen Read exchanged flirty texts with another man two weeks before her cop boyfriend was found murdered, according to testimony Friday.
