PRIOR LAKE, MN — Authorities have charged a Minnesota man in connection with the violent death of his mother and a separate sexual assault incident just one day later.
Aaron Matthew Schlossin, 36, is facing serious felony charges, including second-degree murder, second-degree criminal sexual conduct, and first-degree burglary, according to KSTP.
Police were first alerted Sunday after a concerned individual requested a welfare check at a home on the 4500 block of Colorado Street in Prior Lake, Minnesota.
Investigators say the caller, who hadn’t seen the resident since Thursday, reported an interaction that evening with Schlossin, who appeared “very high and out of it” after doing a “whippit” and asking for a cigarette before returning inside the home.
The same witness noted he hadn’t seen the woman—67-year-old Diana Lee Kaiser—performing her usual routine, such as walking her dog or bringing in her garbage. Schlossin’s car had also been absent since that night.
When officers arrived and looked through a window, they noticed what appeared to be dried blood in the bedroom. Inside, they discovered a woman’s body partially hidden under blankets. The deceased was later identified as Kaiser, Schlossin’s mother.
According to court records, she had suffered significant head and facial trauma. Investigators also found a white-yellow powder throughout the residence, and on top of the victim’s body was a bloody pair of jeans containing Schlossin’s ID.
Neighbors had observed erratic behavior around the time of the suspected killing. One reported seeing a man “acting odd” and skipping through her yard Thursday evening. Another said she heard a violent altercation, describing the sounds as those of a “murder.”
Further insight into Schlossin’s behavior came from his brother, who told police he had cut off contact due to Schlossin’s instability. He recounted an incident where Schlossin allegedly pulled a gun on him over a disturbing plan involving their father.
The next day, Burnsville police responded to a report of sexual assault. A woman told investigators a man had followed her into her apartment and attacked her as she prepared dinner for her child. She said the man groped her before she struck him with frozen meat and managed to fight him off.
Shortly afterward, a separate witness called 911 after encountering a man bleeding from the face, appearing disoriented. The man asked for a ride and claimed to have no memory of how he was injured.
Police later arrested Schlossin, who matched the description of the assailant.
He remains in custody in Dakota County on the sexual assault charges, as authorities continue their investigation into both cases.
Presumption of Innocence: A presumption of innocence means that any defendant in a criminal trial is presumed to be innocent until they have been proven guilty beyond a reasonable doubt in a court of law. The defendant in this case is only accused of the charges set forth in the criminal complaint. They are innocent until proven guilty.
