New details of the events that led to the killing of a Wall Township woman last month in the Glen Oaks Apartments were released today.

The suspect in this case, Alex Williams, allegedly told police he caught his girlfriend cheating on him and admitted making a 911 call earlier that morning where he said he “just killed his girl.”

According to the affidavit of probable cause, that 911 call was made at 9:22 a.m. on May 23. As police were responding to the scene, a witness said they heard the suspect yelling “you cheated on me, you cheated on me” and saw him swinging what they believed was a baseball bat.

The victim was seen groaning, leaning against a car. Her left arm was nearly severed above the wrist. Police found a machete near the victim.

Williams told a Wall Township police sergeant that he “caught her cheating on me.”

Police say the couple had a history of domestic violence. Back on Feb. 24, police were called to the victim’s apartment after she said Williams wrecked her home, stole her phone and stopped her from leaving. Police saw what they described as obvious signs of damage throughout the home and scratches on her arms and hands during that visit. Williams was charged with assault as a result.

Williams is facing murder charges because the victim died a week after the May 23 machete attack. He is being held at the Monmouth County Jail.
