Hector Manuel Castillo, 21, was fatally shot at England Park in Westminster, Colorado, on a December evening in 2014. The shooting occurred after a confrontation at the park; reports say a fight broke out among several people and that Hector and 25-year-old Aaron Castillo (not related) were both shot in the back as they tried to leave. Aaron survived his wounds.

Investigators recovered a weapon near the scene and soon identified a suspect, 16-year-old Israel Jordan Maestas, who was charged as an adult with second-degree murder, attempted second-degree murder and first-degree assault with a deadly weapon. A jury later convicted Maestas, then 17, of reckless manslaughter and assault in connection with Hector’s death.

Hector’s family and the Westminster community were left to reckon with a young life ended in a park altercation. If anyone was at England Park that night or has information about the events leading up to the shooting, please come forward.
