Police say another man who's name has not been released collapsed on a neighbor's front lawn.
He was taken to Rochester General Hospital where he later died due to stab wounds.
Police believe all involved were part of a domestic dispute.
Officers say this is a quiet neighborhood but have been called to this address before for previous disputes.
Police believe a 7 year old boy may be a witness to the crime. He is in police custody and is being interviewed.
We are awaiting word from the medical examiner's office.
We will have a live report tonight on News 8 Now at 5 and 6.
