An investigation is underway in the town of Blue Earth near the Iowa border after a home invasion left one man dead and three women seriously injured.
Officials with the Blue Earth Police Department and the Faribault County Sheriff's Office responded to a disturbance call shortly after midnight Monday.
Officials found several people had been assaulted. A 38-year-old man was dead. Three women were seriously injured and a six-year-old girl was unharmed.
Officers say a masked man entered the home and attacked the victims with an unknown object.
Officials believe the suspect acted alone, said Jill Oliveira,a spokeswoman for the Minnesota Bureau of Criminal Apprehension.
"We're really at this point working to identify suspects in the case, whether this was a stranger, whether this was someone known to the family, we're really still working through that part of the process," Oliveira said.
The three injured women were taken to a local hospital and then to St. Mary's Hospital in Rochester for further treatment. Oliveira said.
