MINNEAPOLIS (WCCO) — St. Paul police say officers made a “gut-wrenching discovery” Friday night in the South Frogtown neighborhood.

A 911 call came in just before 9:30 p.m. to report a mother had not picked up her children from daycare, and she was not answering the door of her house on the 500 block of Charles Avenue. Officers arrived to find the woman, who they described as “gravely injured.” She was later pronounced dead at the scene. Officers also found two children in the home, who were not hurt.

Police arrested a 27-year-old Minneapolis man Saturday morning on suspicion of murder.

The Ramsey County Medical Examiner’s office is working to determine the woman’s cause of death. She has not been identified by investigators.

Anyone with information in this case is urged to contact the St. Paul Police Homicide Unit at 651-266-5650.
