They both died at the end of an Orono cul-de-sac of multiple gunshot wounds, one a prominent OB-GYN physician and the other a 2009 law-school graduate.
But what was the connection?
On Sunday night, authorities still wouldn't say, even after the Hennepin County medical examiner's office identified Ted C. Hoffstrom, 30, a University of St. Thomas law school graduate from St. Anthony, as the armed man who was killed by police Friday night outside the home of Dr. Stephen Larson, 74.
Hoffstrom, suspected of fatally shooting Larson, had a virtually spotless record, and a friendly demeanor, too, friends say.
But authorities on Sunday again declined to provide any further details about Hoffstrom or how the two men may have known one another.
Of the possible links between them, Jennifer Johnson, a sheriff's spokeswoman, said simply: "We can't comment. It's still an active investigation."
The Hennepin County Sheriff's Office is scheduled to hold a news conference on the case on Monday afternoon.
At Hoffstrom's home, family members posted a written statement on the front door expressing sympathy for the Larson family, and added that "many questions remain unanswered."
