Serril Jovan Allen was 19 when he was shot and killed in Denver on the evening of February 14, 2012. He was found near 36th Avenue and Hudson Street with a gunshot wound to the chest and was taken to a hospital, where he later died. Allen had played running back for Ridge View Academy.

Denver Police opened a homicide investigation and publicly asked for witnesses, saying investigators believed more people saw what happened than had come forward. Over time several people have been identified as suspects or persons of interest: Arthur Rivera, Marvin Big Monster McCullough, Jason Quijada, George Mieter, Phillip Munoz, Anthony Casias, and Devonne Burton; there has been no public confirmation of arrests or formal charges.

The circumstances that led to the shooting remained unclear in the immediate aftermath, and the investigation is ongoing. If anyone witnessed the shooting or has information that could help bring justice for Serril Allen, please come forward.
