In a deeply unsettling incident in Minnesota, a man is accused of forcibly entering his former girlfriend’s home and fatally shooting her along with her new partner. This tragic event unfolded while the woman’s child, who was present during the shooting, made a desperate call to the police, reporting that her mother’s ex-boyfriend had shot and killed her, according to law enforcement.

The suspect, identified as 45-year-old Randy Zimmerman, allegedly fled the scene in Brown County following the horrific act. He made his way to Iowa, where he engaged in a dangerous high-speed pursuit with local authorities. During this chase, Zimmerman reportedly fired a shotgun at a pursuing sheriff’s deputy, as detailed by Louisa County Sheriff Brandon Marquardt in a statement to Law&Crime.

Police in Iowa managed to apprehend Zimmerman after using a tactical maneuver to drive his vehicle into a ditch, subsequently capturing him in an adjacent field. Sheriff Marquardt noted that Zimmerman was apprehended with the aid of a taser after a determined chase.

Zimmerman, who has familial connections in Iowa, fled to the state after the early morning shootings on Sunday, around 4:20 a.m. The victims have been identified as Zimmerman’s ex-girlfriend, whose name has not been disclosed, and her new partner, 50-year-old Justin Reinert, a retired firefighter. This information was provided by the Brown County Sheriff’s Office.

According to a press release from the sheriff’s office, the tragic sequence of events began with a 911 call from a juvenile witness. The child reported that their mother’s ex-boyfriend had broken into their home and committed the shootings. Upon arrival, law enforcement found both the 32-year-old woman and Reinert deceased from gunshot wounds.

Authorities found two spent shotgun shells in the upstairs bedroom where the couple was killed. They each died from gunshot wounds to the head. Multiple children were inside the residence, according to cops.

“I gave you a chance,” the ex-girlfriend’s son recalled Zimmerman saying to her right before allegedly opening fire, according to a criminal complaint obtained by Minnesota NBC affiliate KARE. The child said he was asleep and woke up to someone in the home yelling profanities. He allegedly went to investigate and was met by Zimmerman in the hallway outside his bedroom, who ordered him back into the room while pointing his shotgun at the boy.

Police say Zimmerman fled in a 2013 Toyota Camry and spent 12 hours on the run before being apprehended in Louisa County, Iowa. A license plate recognition system located him in Washington County.

“Louisa County and Muscatine County Deputies intercepted the suspect being followed by a Washington County Deputy near X43 and Hwy 92,” the Louisa County Sheriff’s Office says in a press release provided to Law&Crime. “The suspect vehicle would take off at a high rate of speed before any stop was initiated.”

Zimmerman was allegedly traveling at speeds “over 100 mph” when he opened fire on the Louisa County deputy, who was not hit.

Zimmerman was arrested on felony murder warrants from Minnesota and booked in the Louisa County Jail on a $5 million cash-only bond. He waived extradition and was awaiting transport back to Minnesota. He has previously been arrested for stalking, though it’s unclear if the charge was related to his ex-girlfriend. He also has past convictions for domestic assault, assault, burglary and DWI. Iowa police plan to charge him for opening fire on a sheriff’s deputy and evading arrest.

“We do plan on filing charges and will be asking for a warrant to be issued,” Marquardt told Law&Crime.
