Brian Simms Jr., 24, of Olathe, Kansas, was shot dead in an Oklahoma City parking lot after a concert at the Farmers Public Market. Two off-duty police officers working as private security, Sgt. Paul Galyon and Officer Antonio Escobar, found Simms asleep in his car and saw a handgun in his waistband. According to the officers, Simms did not follow commands and confronted them; Sgt. Galyon then fired multiple times into the vehicle. Simms was struck repeatedly and died at the scene. The Oklahoma Medical Examiner ruled the death a homicide.

An internal Oklahoma City Police Department review concluded Sgt. Galyon’s actions were justified, and the Oklahoma County District Attorney declined to file criminal charges. Simms’s mother later pursued a federal wrongful death lawsuit; the court granted qualified immunity to the officer. Officer Escobar did not fire his weapon. What details about the encounter or the subsequent investigations would help clarify what happened that night?
