WATCH: Gay Man Killed by San Diego Police After Domestic Dispute

A gay man in San Diego is dead after police opened fire on the man suspected of threatening his boyfriend with a butcher knife, reports San Diego TV station KSWB.

The deceased has not been publicly identified, but is believed to have shared a residence with his boyfriend at Mercy Gardens, a low-income residential facility for people with disabilities in San Diego's LGBT-heavy Hillcrest neighborhood. He was 30 years old, according to San Diego's KGTV.

Police responded to a report of a domestic dispute between the two men around 10:35 p.m. Friday, where one allegedly held a butcher knife to his boyfriend's throat. A police helicopter soon spotted the suspect a block away, still carrying the knife.

"The suspect did not comply with the officer's demands of dropping the knife," San Diego Police Department Capt. David Nisleit told KSWB. "The officer, fearing for his life, fired one round, striking the suspect."

The suspect was transported to a local hospital, where he died from his injuries. Police told media the suspect was wanted for a parole violation, and had a "violent criminal history." The man's boyfriend was not injured in the earlier domestic dispute.

The officer who fired the fatal shot, a 13-year-veteran of the force, was not injured, and reportedly captured the incident on his body camera. That video has not yet been released.
