Minneapolis police said they found the body of an Arena, Wis., woman murdered in her home earlier this week.

Lois Swenson, 76, died from multiple blunt-force injuries, according to police.

Investigators found Swenson’s body Wednesday afternoon during a welfare check.

No arrests have been made.

Friends of Swenson said she was heavily involved in social justice, peace and environmental issues.

She worked as a teacher for many years, they added.
