Wisconsin Rapids Police are looking into two deaths that happened Friday.
One investigation involves a 34-year-old Antoini Quinones, who was brought to a hospital with life threatening injuries and died from those injuries.
He had apparently been hurt the day before at a private residence.
Also Friday, Wisconsin Rapids officers were called to a home on 11th Street South with a report of a disturbance.
They found 56-year-old Randall Harris Sr. suffering from life threatening injuries.
He was pronounced dead at the scene.
His son, 34-year-old Randall Harris Jr. has been taken into custody as a suspect in the death.
While the incidents happened at about the same time, detectives do not believe there is any connection between them.
