EDMOND, Oklahoma -- Police have identified the man shot and killed at an Edmond home Sunday afternoon as 24-year-old Michael Ford. He was living in Moore and showed up at his ex-wife's home Sunday.

Investigators say Ford threatened at least one person in the home with a hunting knife. That's when another man shot and killed him.

Investigators say Michael Ford showed up to a home near Danforth and Santa Fe Sunday afternoon, and a verbal fight broke out between Ford, his ex-wife and another man inside.

"There was an altercation, he had gone to his vehicle, which is a truck, parked in the driveway, went and got a hunting knife and had come back in and threatened the shooter with a knife," Edmond Police Department spokesperson Jenny Monroe said.

Police say Ford, wielding a knife, back the man up against a wall. That's when the man fired his .40 caliber handgun, killing Ford with three shots to his head and chest. At this point, investigators say the shooter isn't facing any charges. They believe he was acting in self-defense.

"That's what we're trying to look into today, but that is how it appears and we're just trying to make sure that's exactly what happened," Monroe said.

Ford still had a key to the home. Neighbors say he'd just moved out a few months ago, but police say Ford had no right to be there. Now they're trying to piece together the events that led up the deadly fight.

Monday, police interviewed family members and neighbors who knew Ford and the other two people involved. Police have not arrested anyone in the case.

Neither the shooter nor Ford's ex-wife were injured during the fight. We're told the couple has a young child, but fortunately, he wasn't home at the time of the shooting.
