Police Sgt. Paul Paulos said officers found the bodies of two men and one woman when they were called to a duplex apartment Sunday afternoon, the St. Paul Pioneer Press reported Monday.
Paulos didn't elaborate on whether it was a double homicide-suicide.
He said two of the victims were a married couple and the other man was related to the woman.
Police radio traffic indicated a dispatcher said "somebody with an extreme language barrier" reported "the husband was killing the wife," the Pioneer Press said. Police reported a possible stabbing victim, then said "two more down."
Several children were in the home at the time of the incident. They were placed in the care of relatives, Paulos said.
