Felipe Jason Moreno was 20 when he was shot and killed on December 22, 2012, in San Bernardino, California. The shooting happened around midnight as Moreno and his cousin, Daniel Gomez, were driving away from a large End of the World party tied to the Mayan calendar buzz. Moreno suffered a fatal gunshot wound to the upper torso and the vehicle rolled to a stop; Gomez was also shot in the arm.

Investigators recovered two different types of shell casings, suggesting the possibility of multiple shooters, but no suspects have been identified. The gathering had been mostly non-violent until the shooting, and police say little cooperation from the many attendees has hindered the probe. Authorities continue to ask anyone with information to come forward.

If anyone attended that party or has information about Moreno’s killing, please share what you know with investigators.
