A man accused of killing his mother in their Prior Lake home last week is being held for allegedly breaking into a Burnsville home and groping a woman a day later, according to court documents.
Diana L. Kaiser, 67, was found dead by Prior Lake Police Department officers in her home on the 4500 block of Colorado Street Southeast on April 27, according to a criminal complaint filed in Scott County District Court. Police were dispatched to the home for a welfare check after neighbors became concerned they hadn’t seen Kaiser in days.
According to the complaint, a neighbor told officers upon arriving at the home that they spoke to Kaiser’s son, Aaron Matthew Schlossin, on the evening of April 24. Schlossin had stepped outside of the house to do a “whippet,” or inhale nitrous oxide to get high, and asked the neighbor for a cigarette.

Another neighbor reported to police they had heard the sounds of a woman screaming coming from the house at about midnight on April 25, followed by a man yelling. The neighbor told officers it “sounded like someone was being murdered,” and that the sounds stopped at about 1 a.m., according to the complaint.
When officers searched the exterior of the house on April 27, they saw a leg sticking out from a pile of blankets on the floor of a bedroom, along with blood-stained sheets and mattress. The complaint said officers entered the house and found Kaiser under the pile of blankets, apparently dead for several days.
Schlossin, 37, has been charged with second-degree murder. He was already in law enforcement custody after being arrested in Burnsville a day later.
Schlossin allegedly entered a sliding door of a home and groped the female occupant, according to charges filed in Dakota County. The woman fought Schlossin off and he left the home.
Soon after, a woman called 911 after seeing Schlossin stumbling and bloody-faced. She told first responders Schlossin had said he didn’t recall how he became injured.
He faces charges of second-degree criminal sexual conduct and burglary for the Burnsville incident, and remains in custody at the Dakota County Jail in Hastings as of Wednesday, April 30.
An online search of court records shows a history of traffic violations and petty misdemeanor drug convictions for Schlossin, but no history of serious or violent crimes. According to the Scott County complaint, neighbors report Schlossin had told them about his history of mental illness.
