Watch as Matthew McCabe testifies about the events leading to John O'Keefe's death in Canton, Massachusetts. Earlier, Karen Read's defense team questioned witness Colin Albert, who was at the house outside of which O'Keefe's body was found hours earlier. (NOTE: The livestream is muted during breaks and non-public discussions. The court has prohibited the recording of any minors called as witnesses, along with exhibits showing prior interviews of them.)
