A man charged in the deadly shooting of a 25-year-old Minnesota National Guard sergeant in St. Paul last August has changed his plea from not guilty to guilty.

Twenty-six-year-old Aaron Allen of South St. Paul has pleaded guilty to second-degree murder in the death of Brandon Horst.

As part of his plea Allen agreed to testify against 25-year-old Heather Horst who is also facing murder charges in the case. She is accused of plotting to kill her husband Brandon. 

Heather Horst previously entered a not guilty plea in his murder.

Allen was Heather Horst's sister-in-law's fiancé. The pair's motive for the killing was Horst's life insurance policy, according to the charges.

Brandon Horst was shot in the head around 1:11 a.m. Monday, Aug. 5, while lying in his bedroom at the couple's home, 468 Bellows St., the charges said.

Brandon Horst had a $400,000 military life insurance policy and an $80,000 life insurance policy from the federal government for his position as a federal technician, according to the charges. Heather Horst was the sole beneficiary for the policies.

According to the Ramsey County Attorney's Office, Allen admitted to the prepping, planning and executing of the murder with the help of Heather Horst in exchange for a percentage of the life insurance policy. He also said Heather Horst drove him to her house and told him where her husband was sleeping. He said she drove him away from the scene to dispose of the murder weapon.

Allen will be sentenced Tuesday, April 22. A court date has not yet been set for Heather Horst.
