Diane Fortenberry, 51, had lunch with friends on Friday and returned to her rural Osakis home to tend to her dog.
That's when she reportedly walked in on a burglary in her home.
She was assaulted and died from blunt force trauma injuries, according to preliminary autopsy results.
Fortenberry's son found her when he returned home around 4:40 p.m. Friday. She was transported to Long Prairie Hospital where she was pronounced dead.
The Fortenberry's home is located near the northwest side of Lake Osakis, along County Road 10 in Todd County.
No arrests have been made in connection to the homicide.
Todd County Peter Mikkelson is asking for the community's help in finding the killer.
"We urge anyone in the area who may have seen anything unusual to contact us," Mikkelson said.
"You know what's normal in your neighborhood. If someone has come to your door asking for directions or offering tree cutting services or selling something, give us a call," the sheriff said.
On Sunday, Sheriff Mikkelson released a detailed list of items taken from the Fortenberry's home.
"We're hoping citizens see someone with some of these items and contacts us," he said.
The following items were taken in the burglary:
A large amount of collector coins and currency including rolls of Susan B. Anthony and Eisenhower silver dollars, buffalo nickels, wheat pennies, indian head coins, $5 silver coins, $2 bills and silver C notes $100 bills;
32 inch Westinghouse flat screen TV;
