Jose Cruz Prado was 29 when he was found dead in a trailer home in Ada, Oklahoma, on Thursday, September 24, 2015. Authorities determined his death resulted from gun violence and treated the case as a homicide.

Investigators said the inquiry moved quickly: detectives interviewed witnesses and gathered evidence, and within weeks law enforcement identified multiple people they believed were connected to the crime. The investigation was publicly linked to another criminal matter at a local race track, and authorities named at least three suspects in connection with Prado’s murder.

Few personal details are provided beyond his age and place of death. Does anyone have information about Prado, his connections to the race track, or the events in Ada that fall that could help clarify what happened?
