Luis Velasquez-Mejia, 26, was fatally shot in the neck on Saturday night, December 22, 2018, in the Excelsior neighborhood of San Francisco. He had attended a birthday party earlier that evening with a friend, Jonathan Escobar, and a cousin; afterward the three went to the cousin’s house. The cousin went to take a shower and then heard a loud noise and screaming. Escobar allegedly burst into the bathroom saying he had killed Velasquez-Mejia and warning the cousin not to snitch. The cousin called 911 and Velasquez-Mejia was pronounced dead at the scene.

Investigators identified 22-year-old Jonathan Escobar as the primary suspect and located him the next day at a residence on 24th Street. He refused to surrender, climbed onto the building’s roof and threatened to jump before a two-hour standoff ended with his arrest. Escobar was booked on suspicion of murder; prosecutors allege a semi-automatic handgun was used. He had prior arrests for assaultive behavior, was subject to a civil protective order barring him from carrying a firearm, and was arraigned in San Francisco Superior Court where he did not enter a plea and was held without bail.

Does anyone have information about Velasquez-Mejia’s last movements that night or about the events at the cousin’s home?
