Williams, who is dating Cook’s ex-husband, was found with at least two gunshot wounds to her torso and ultimately died.

Police learned Cook had come to the apartment to deliver cold medicine for one of the twin 3-year-old children the couple had from their previous relationship.

Cook remained in the apartment unlawfully after being asked to leave, and locked herself in a bathroom.

The woman eventually left the bathroom and walked toward her coat, but suddenly pulled out a handgun and fired three to five rounds at Williams, according to the statement of probable cause.

Williams fell to the couch after being shot.

Cook’s ex-husband took the handgun away from her and went to help Williams, and Cook sat down on a chair. When Cook got up moved back toward her coat, he pinned her against the wall until police arrived.
