Antwan Bluthenthal, 46, was shot and killed in the hallway of a third-floor corridor at 701 Sixth Avenue in San Diego’s Gaslamp Quarter on the evening of August 3, 2025, after visiting the Cielo Rooftop Lounge on the building’s fifth floor. Police and paramedics found him with at least one gunshot wound; despite first aid at the scene, he died of his injuries.

Witnesses inside the building detained a man on the sidewalk and pointed officers to a recovered handgun. Detectives said the confrontation began as a physical altercation between two people and escalated when one produced a firearm. Investigators reported both men had been patrons of the rooftop bar and did not believe the victim and the suspect knew one another before the encounter.

Police arrested 37-year-old Bryan Tyner on suspicion of murder; he was booked into county jail and later arraigned in San Diego Superior Court, pleading not guilty to murder and a misdemeanor count of carrying a concealed firearm. A judge declined to set bail, and a preliminary hearing was scheduled for January 13, 2026, with Tyner remaining in custody.

If anyone witnessed what happened in the building that night or has information about movements inside the rooftop lounge or the elevator access, please share what is known.
