Officials believe a 40-year-old man killed his father and his father's fiancee in Shakopee, and then drove to Waseca where he killed himself following a standoff with police.
Police discovered the bodies of a 68-year-old man and 67-year-old woman when they did a welfare check at their home on Dakota Street in Shakopee around midnight Tuesday, a news release says.
During a press conference, Shakopee Police Chief Jeff Tate described the scene officers walked into as "brutal."
The couple, who were engaged, died of apparent "blunt force trauma," according to police, and were lying next to each other when police found them, the police chief told BringMeTheNews.
He said they were found in a "utility type room."
During their investigation, police discovered the female victim's car was missing – it was later located in Waseca, where the male victim's adult son lives, a news release Tuesday afternoon said.
At around 9:30 a.m., police tried to make contact with the suspect, the Waseca County News reports.
That's when police say he barricaded himself in a room with a gun. Negotiators tried for hours to get him to come out, a news release says, but at around noon police said he was found dead at the scene from a self-inflicted gunshot wound.
Officials say they aren't looking for anyone else connected to the killings, and had stressed that the public was not in danger.
The identities of the victims haven't been released – the Hennepin County Medical Examiner's Office will do that, along with determining the cause and manner of their death. But neighbors have identified them as Terry Weimer, who owned the home, and Renee Ahrens, Shakopee Valley News reports.
Officials have not released the identity of the suspect, but they say he has a criminal history of assaults as well as drinking and driving.
The police chief says the Bureau of Criminal Apprehension's crime team will go through the entire house to try to figure out what happened. Investigators will also try to determine why this happened by looking into the days leading up to the murder.
