The second trial of Karen Read, the Massachusetts woman accused of killing her police officer boyfriend John O'Keefe, will be delayed until Friday because of heat, Judge Beverly Cannone told the court.

Cannone's announcement came after a half-day of testimony from a snow plow driver and a resident who went to a bar with Read and O'Keefe the night before he was found dead. Citing the 90-to-95 degree temperatures expected in Massachusetts on June 5, Cannone opted to give the jury the day off.

Before the delay, the court heard testimony from Brian Loughran, a snow plow driver for the town of Canton, who said he did not see O'Keefe's body in the yard of now-retired Boston Police Officer Brian Albert, where O'Keefe was found dead on Jan. 29, 2022. He told the court he passed by the house multiple times on his route beginning around 2:45 a.m.

The state grilled him about his memory and recollections, citing different statements Loughran gave over the years regarding the times he passed Albert's house and when his shift ended. Prosecutor Hank Brennan also pressed Loughran about whether he felt intimidated by an unnamed internet blogger.
