Karen Read, accused of killing a Boston police officer, seeks Supreme Court intervention for retrial.

Karen Read, accused of killing her boyfriend, a Boston police officer, is facing a retrial. Her lawyers have asked Supreme Court Justice Ketanji Brown Jackson for a stay, arguing that a previous unanimous but unannounced jury decision could protect her from double jeopardy if found not guilty in the retrial. The case is complicated by the first trial's hung jury, and the retrial's jury selection is ongoing in Massachusetts.
