A Minnesota man has pleaded guilty to killing two people last November before leading police on a chase in Iowa.

Randy Thomas Zimmerman entered guilty pleas in the murders of Tabitha Trescott and Justin Reinarts. Trescott was Zimmerman's ex-girlfriend and Reinarts was a long-time firefighter in Hanska.

A child told deputies that he woke to someone yelling profanities and saying, I gave you a chance. He told law enforcement that he then heard a discharge from a firearm. The child said he opened his bedroom door into the hallway and saw Zimmerman, who allegedly pointed a long gun at him and told the boy to go back to his room. The young witness complied, waiting a time before calling 911.

Hours after the murders, sheriff's deputies in Louisa County, Iowa, were notified of a double homicide suspect from Minnesota driving east on Highway 92. Deputies from multiple counties responded and intercepted the suspect vehicle and gave chase.

Louisa County sheriff's officials say Zimmerman refused to pull over, taking off at speeds over 100 mph. They say the suspect fired a shot at pursuing squads but did not hit anything. A PIT maneuver eventually disabled Zimmerman's vehicle, and the suspect ran from his car and fled on foot. Deputies caught him and took the alleged shooter into custody. The shotgun believed to have been used in the murders was found near the vehicle.

Zimmerman faces a sentence of life in prison.
