The subject of a manhunt following a double homicide in Michigan last week has been formally charged.
Zachary Patten, 32, was formally charged Monday with four counts - including open murder, felony murder and 1st degree home invasion in connection to the shooting death of 29-year-old Shane Richardson.
Patten was arraigned from the St. Joseph County Jail two days after he was extradited to Michigan from Indiana. He turned himself in to police officers in South Bend just before noon Friday morning after a statewide manhunt.
Around 10:15 p.m. Thursday night, police said Patten drove to his ex-wife's home in Constantine. According to the criminal complaint, Patten was armed with a pistol and got into an altercation with his ex-wife's husband, Shane Richardson, before shooting and killing him.
Patten is also facing one count of felony firearm.
Police said about 40 minutes before Richardson’s murder, Patten shot and killed a 31-year-old mother of four while she attempted to break up a fight between Patten and her brother.
Charges for the Kalamazoo murder have not yet been submitted by the prosecutor.
KDPS officers said they are close to wrapping up their investigation and expect to file charges as early as Tuesday.
