Man got into a fight with his girlfriend's ex-boyfriend. Hours later, he executed the ex in a driveway.

A Newport, Minnesota man argued over the phone with a woman’s ex-boyfriend. Hours later, the ex was murdered execution-style.

The killer will now spend the next five decades behind bars.

On Sep. 15, Dakota County District Judge Timothy McManus handed Jerome D. Misters, 37, a 55.5-year sentence in prison for the shooting death of Matthew Perkins, 33, and the wounding of a 36-year-old Bayport man. He was found guilty and convicted by a jury for one count of second-degree intentional murder and one count of attempted second-degree murder.

The defendant received 40 years for the murder charge and 15.5 years for the attempted murder charge.

In the morning hours of Aug. 17, 2020, police in Dakota County responded to the 600 Block of 17th Avenue after a shooting report. Upon arrival, officers found Perkins face down on the sidewalk after being shot five times, according to media reports. He died soon after.

A few yards away, Perkins’ cousin was also found with a gunshot wound to his abdomen and upper arm and survived.

During interviews, the woman who had let Misters live at her home told investigators that her ex-boyfriend, Perkins, and Misters got into an argument on the phone. The ex-boyfriend blamed Misters for ruining his life, local media reported.

After the couple went to bed, Misters told her that he received a threatening text from the victim who was waiting outside the home. The woman followed and testified seeing a wounded man on the ground and Misters standing over Perkins shooting him multiple times.

The police described the shooting as an execution.

"The sentence issued by Judge McManus was warranted in this case given the senseless violence perpetrated by Misters against two separate victims," said County Attorney Kathy Keena in a statement according to Star Tribune.

Though Misters was ordered to serve both prison terms consecutively, he will spend 36.5 years behind bars due to credit for time spent already while in custody. The rest of the sentence will be served on supervised release.
