Two people were charged Monday in connection with the fatal shooting of a Minnesota National Guard sergeant, one of which was his wife.
Aaron William Allen, 25, and Heather Leann Horst, 24, both of St. Paul, were each charged with second-degree murder and conspiracy to commit a felony in the death of Brandon James Horst, 25, a staff sergeant with the Minnesota National Guard's 133rd Security Force Squadron.
Allen's fiancee eventually told police Horst and Allen had conspired to kill Brandon Horst because Heather Horst could no longer stand their arguing.
According to charges, on Aug. 5 at 1:11 a.m., Heather Horst called 911 and reported her husband Brandon Horst was in bed with a lot of blood coming from his head. She repeatedly said she didn't know what had happened, but that the door was unlocked when she got home.
Heather Horst said she and her husband had been arguing for several days about her husband's proposition they have an open relationship, according to charges. Horst said the two made amends by 10:30 p.m. on Aug. 4.
Paramedics found Horst with one gunshot wound to his head. He was pronounced dead at 1:19 a.m. An autopsy revealed that the manner of death was a cerebral laceration and destruction due to a gunshot wound.
No firearms were found in the area where Horst had been shot, but a single 9-mm. casing was found on the bed.
Horst told police there was a pistol in the home and led police to a wine cabinet, but there was no gun in the designated drawer. She couldn't recall the make, model or serial number of the missing gun.
Horst said she left after her and her husband made amends to pick up Brandon Horst's step-sister, who is Allen's fiancee, and the two went to Walgreens. Further investigation indicated that the two women had driven to Walgreens in west St. Paul and surveillance video showed that they left the parking lot at approximately 12:37 a.m.
Allen's fiancee told police that Allen was returning to their apartment -- one the pair shares with a roommate -- from a walk when Horst arrived and two women left for Walgreens. She told police the two then planned watch a movie with Brandon Horst.
Allen's roommate also told police that Horst was upset over having lost a baby. According to the charges, the roommate also overheard Horst saying her husband abused her and the only way she could leave their marriage or be free from him was if he was dead.
On the night Brandon Horst was shot, the roommate could not tell police when Allen had left the apartment; however, the roommate did recall that Allen returned out or breath at about 1 a.m.
Police recovered five deleted text messages from Heather Horst's phone between her and Allen shortly after midnight on Aug. 5:
-12:06 a.m., Allen texted Heather Horst, "You gitta hurry."
-12:08 a.m., Heather Horst texted back, "On my way."
-12:10 a.m., Allen texted Heather Horst, "Ivthink I just heard talking."
-12:15 a.m., Allen texted Heather Horst, "He is stillvawake."
-12:17 a.m., Allen texted Heather Horst, "And tyler won't shut up there is a tv on upstairs."
Tyler was later identified as one of the Horsts' dogs.
Allen's fiancee agreed to be interviewed by police again following the recovery of the text messages and said Heather Horst came to her and Allen's apartment on Aug. 4 and said, "I want him dead," explaining that she and Brandon Horst had been arguing and she couldn't take it anymore.
According to charges, Allen's fiancee told police she and Horst picked up Allen after leaving Walgreens and that Horst left the gun for Allen on the dining room table. Allen then waited in the basement for Brandon Horst to fall asleep. Allen told his fiancee he took "one or two shots to the head" and left after he thought he heard police.
Horst and Allen will made their first court appearances on Monday afternoon. Bail for Horst was set at $300,000 with conditions, and her defense attorney told FOX 9 News her family may be able to come up with that amount. Bail for Allen was set at $1 million.
Brandon Horst will be interned at Fort Snelling National Cemetery. The family says memorials are preferred.
