DES MOINES, Iowa (AP) – Police say a man suspected in the killings to two Des Moines area officers surrendered to a state Department of Natural Resources officer.

Des Moines police Sgt. Paul Parizek says Scott Michael Greene flagged down the officer Wednesday morning in rural Dallas County, west of Des Moines, and presented his identification.

He was taken into custody and is now being treated at a Des Moines hospital.

Greene is suspected in the shooting deaths of Urbandale officer Justin Martin, with the force since 2015, and Sgt. Anthony “Tony” Beminio, who joined the department in Des Moines in 2005.

Martin was single. Beminio was married with children.

Parizek says Greene is suspected in the killings but hasn’t yet been charged.
