Neighbor Charged With Assault After Death of Waterbury Man

A Waterbury man is dead and police have arrested a neighbor who is suspected of assaulting the victim.

Police said they responded to 36 Jewelry St. in Waterbury just after 8 p.m. Saturday to investigate a report that a man was unconscious and bleeding from the head.

Police identified the victim as 61-year-old Keith Sullivan and said he was transported to Mary’s Hospital, where he was pronounced dead just before 4 a.m. Monday.

The initial report was that Sullivan might have accidentally fallen down three porch stairs and hit his head on the cement, police said, but detectives determined that he was not injured from an accidental fall.

Daniel Rosario, 35, is accused of assaulting Sullivan and was charged with first-degree assault. He is being held on a $350,000 bond.

The Office of the State Medical Examiner is investigating the cause of Sullivan’s death.
