Despite the official reports, which claimed Champommier drove his car into a sheriff's deputy, causing officers to open fire, Champommier's family says the teen was shot without provocation or justification.
Champommier's mother, Carol, is now suing the DEA, LAPD and LA County Sheriff's Department in federal court for wrongful death.
According to the lawsuit, first reported by Courthouse News Service, Champommier was in his car waiting for a friend when he saw officers detain someone. When Champommier began to drive away toward the parking lot exit, he was fired upon.
Champommier "was unarmed, had not threatened the agents/officers, did not pose a threat of death or serious physical injury," states the lawsuit. The officers "proceeded to use unreasonable, unnecessary and excessive force, firing multiple bullets and killing" Champommier.
Champommier's mother also claims that after her son was killed, the officers and agents "gave false statements, concealed material information, tampered with evidence, and otherwise attempted to cover up their misconduct."
