A woman’s roommate found her beaten to death on a mattress located on the floor of their living room in front of a couch in the apartment they shared. The roommate denied participation in the homicide. The victim had sustained severe blunt force injuries of the head. The location of impact spatter on the left edge of the couch and wall behind indicated that blows were struck to the victim while her head was consistent with a sitting position as well as in her final position. Multiple cast-off stains were present on the ceiling over the mattress. A bloodstained aluminum softball bat, which exhibited multiple dents, was located in the bathroom. The blood on the bat was determined to be consistent with that of the victim.
