UPDATE: Suspect in Michigan murders arrested in South Bend

A man wanted for killing two people in Michigan gave himself up to South Bend police officers on Friday.

Zachary Patten crashed his car near the South Bend airport around midnight, and was tased when he wouldn't comply with officers orders.

He then went to the hospital. Hours later, it appears Patten was done running and turned himself into the first officers he could find.

Officers were at Martin's on S. Mayflower for a shoplifting call when they say Zachary Patten approached them and said he needed to be arrested.

Patten was wanted for shooting and killing two people Thursday night in Kalamazoo and St. Joseph County, Michigan.

“Just luck,” St. Joseph County Metro Homicide detective Chris Kronewitter said.

A lucky end to a chaotic Friday for detectives in South Bend.

"You just don't see a double homicide suspect walk up and say 'I wanna turn myself in'," Det. Kronewitter said.

But that's exactly what happened outside a Martin's supermarket on Friday.

"He said he believe he needed to go to jail. They asked why and he said he shot a couple people up in Michigan," Det. Kronewitter said.

The shootings were first reported Thursday night in Kalamazoo at a mobile home park where police say Patten shot a woman. They say he then drove to a home outside Constantine where he shot a man who married his ex-wife.

"His wife did come to one of our yard sales and they were expecting their first baby together," one neighbor said.

Patten crashed his car near the airport, was tased, hospitalized then released. Hours later, detectives say Patten's demeanor greatly changed.

"Very calm," Det. Kronewitter. "It just seemed like he wanted to be helpful."

Patten was questioned by detectives from Michigan, and is now in a South Bend jail cell awaiting his day in court.

Police say the woman killed in the Kalamazoo mobile home park was a bystander who was nearby as Patten was arguing with a man.
