Aaron Schlossin has been indicted this week by a Scott County grand jury on two counts of first-degree murder in connection with the death of his mother, Diana Kaiser, at their shared residence in Prior Lake. The charges are premeditated first-degree murder and first-degree murder while committing criminal sexual conduct.

On April 27, 2025, Prior Lake police officers responded to a welfare check at a home in the 4500 block of Colorado Street in Prior Lake, which was occupied by Kaiser and Schlossin. While looking through a window, a sergeant observed what appeared to be a leg protruding from a pile of blankets on the floor. Officers forced entry into the residence.

Inside, they discovered Kaiser’s body on the bedroom floor. The 67-year-old woman had suffered significant blunt force trauma to her head and face. Evidence at the scene included extensive blood spatter on the walls, ceiling and windowsill, as well as a bloody handprint on the wall that appeared larger than that of a female.

A pair of bloody jeans was found lying on top of Kaiser’s body. Inside one of the pockets was Schlossin’s wallet containing his identification.

The Minnesota Bureau of Criminal Apprehension (BCA) was called to process the scene and collect evidence.

Dr. Amanda Spencer of the Hennepin County Medical Examiner’s Office conducted the autopsy and determined that Kaiser died as a result of complex homicidal violence. She sustained multiple blunt force injuries to the face with associated fractures, as well as multiple cut and stab wounds.

Schlossin was arrested a day after Kaiser’s body was found after he allegedly entered a home in Burnsville through a sliding door and groped a female occupant who fought him off. He was later picked up by police.

“To commit matricide is completely unfathomable, and to do so with such cruelty is heinous. The facts of this case were presented to the grand jury, which determined these charges were appropriate,” Scott County Attorney Ron Hocevar stated following the indictment. “Mr. Schlossin will now face the consequences of his actions in intentionally causing the death of his own mother. This office will do everything in its power to secure a conviction and administer the severest justice that the state of Minnesota allows.”

Prior Lake Police Chief Liam Duggan said, “Any murder is difficult for surviving family members, but to have a sibling accused of killing your mother is on another level. Our hearts go out to all who are affected by Ms. Kaiser’s senseless murder, particularly her surviving family.”
