GROVE CITY, Ohio (AP) — A central Ohio man killed his ex-wife outside an apartment when she arrived to pick up their two children, and their 13-year-old son called an emergency dispatcher to report the stabbing, police said.

The boy called 911 after the slaying Sunday in Grove City, just southwest of Columbus.

“My dad just killed my mom. He just told me to call you guys,” the boy said in a recording of the call. “He just ran out and killed my mom, and she’s laying in the grass in front of our apartment.”

As the dispatcher called for officers to respond to the scene, the boy pleaded for police not to harm his father.

“Please, guys, don’t do anything to him in front of me, please,” he said. “He has no weapons.”

The boy apparently then handed the phone to his father, who told the dispatcher that he didn’t intend to harm anyone else and that the only weapon he had was a knife that was left outside with the body. He asked if he could kiss his children, told them he loved them, then said he was going to the front door to meet the police.
