Police in the Minneapolis suburb of Brooklyn Park gave new details of the triple slaying early Monday morning.
Spokesman Todd Milburn says the woman had just dropped off her toddler and spoken with someone in the house. As she was leaving the area, she saw a man acting suspiciously.
The woman called the day care back, and was talking to someone when the line went dead. She returned to the home and found three people had been shot. Her toddler was in the house unharmed.
Police say they have made no arrests.
