MIAMI (AP) — The family of a 22-year-old man killed in a barrage of police gunfire during a hip-hop Urban Beach Week festival in 2011 filed a civil rights and negligence lawsuit Tuesday seeking damages for his death and hoping to figure out what happened.

Attorney Marwan Porter said the family believes the killing of Raymond Herisse was unjustified. Officers fired more than 100 shots at Herisse’s car after police said he was driving erratically on Miami Beach and hit one officer. An autopsy showed Herisse was struck at least 16 times. His blood-alcohol level was above Florida’s 0.08 legal limit.
