Prosecutors say Read, 45, backed her SUV into Boston police Officer John O’Keefe, 46, after dropping him off at a party hosted by a fellow officer in January 2022 and left him to die in the snow. Defense attorneys say she was a victim of a conspiracy involving the police and have suggested he was killed by someone inside the home.

The US Supreme Court issued a ruling saying they would not allow some charges to be dropped against Read in her appeal over double jeopardy.

The nation's highest court declined to hear Karen Read's double jeopardy appeal. Why it matters: Read has exhausted virtually all her legal options to get two of the three charges against her dropped before a second jury can weigh in.
