(CNN) — After nearly eight weeks of testimony, jury deliberations began in the retrial of Karen Read for the death of John O’Keefe, following closing arguments from Massachusetts prosecutors and defense attorneys presenting competing narratives about how the off-duty Boston cop died in January 2022.

The Commonwealth of Massachusetts and the defense attorneys for Karen Read are expected to give jurors their closing arguments on Friday as her retrial for the death of her boyfriend, John O’Keefe, nears its end.

Read's lawyers say John O’Keefe was beaten, bitten by a dog, then left outside a home in Canton in a conspiracy orchestrated by the police that included planting evidence against Read.
