The case out of Dedham, Massachusetts, has turned into a yearslong whodunnit legal saga that has captivated true-crime fans across the country.

Evidence about a prior fight between Karen Read and John O'Keefe may be allowed in court after defense team's questioning created an opening for prosecutors.

Jurors sitting on the high-profile case became privy to a slew of text message exchanges that showed a flirtation between the woman charged with killing her boyfriend and an ATF agent who was a friend of the dead man,

Yuri Bukhenik, a Massachusetts State Police trooper, read dozens of text messages between Karen Read and Brian Higgins, an ATF agent.

Massachusetts State Police Sgt. Yuri Bukhenik testifies in a case involving Karen Read, who is accused of hitting her boyfriend with an SUV and leaving him to die.

The protesters fighting the court’s buffer zone in the high-profile Karen Read case have scored a win in federal appeals court. The buffer zone around Norfolk Superior Court in Dedham was expanded for the Read retrial after jurors during the first trial reported that they could hear loud protesters during deliberations.

Jurors also heard from two people — Ryan Nagel and Heather Maxon — who arrived at 34 Fairview Road in Canton, where O‘Keefe’s unresponsive body was found, at the same time as Read and O‘Keefe did shortly after midnight on Jan. 29, 2022.

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.
