The Milwaukee County Medical Examiner's office stated that police responded to a house at around 3.45 pm to assist with a welfare check at a residence, where four men and one woman were discovered to be dead.
According to Milwaukee Assistant Police Chief Paul Formolo, a sixth body was later found.
“Citizens of our community had concerns with the occupants that resided there,” Mr Formolo told CBS. “It’s a normal call for us to respond to. We do it all the time.”
None of the victims have been identified at this time, while the motive for the suspected killings also wasn't immediately clear. Police Chief Formolo added that there is no evidence to suggest that an additional threat remains to the community.
The city’s acting mayor, Cavalier Johnson, sent out his condolences to the friends and family of the victims in a statement on Sunday night.
“The murders discovered today on a residential block in the heart of our city are horrific,” he said.
“First, I offer my condolences to the families and friends of the victims. Whatever the circumstances, we must share the grief of those who have lost loved ones.”
Already this year, 21 homicides have been reported in Milwaukee, according to the county medical examiner’s office. As WDJT reports, this represents a sharp increase from this time last year, when it was at nine.
Autopsies will be performed Monday, the medical examiner’s office also confirmed.
