The death of a Bronx man — who was discovered with a puncture wound to the neck inside his home last week — has been ruled a homicide, police announced Monday.

Aaron Bonnett, 31, was discovered Tuesday night inside his home at East 178th Street and Vyse Avenue in West Farms, lying on the floor of his bedroom with a neck wound and head trauma, cops said.

There was no sign of forced entry and police say they suspect Bonnett’s girlfriend may have been involved.

Bonnett’s father first alerted authorities because his son wasn’t answering his phone calls, according to officials.

No arrests have been made, but the victim’s significant other remains a person of interest in the case, police said.
