Arian was fatally shot by police after a freeway chase and confrontation in which police say the teenager claimed he had a gun. Officers fired as many as 120 bullets at Arian, hitting him more than a dozen times.

But police found no weapon on Arian or in his car. What they did find was Arian's cellphone, which he allegedly held toward the cops before they opened fire.

Jeffrey Galen is the Arian family's attorney. Galen says officers should have been able to tell that Arian was not
holding a weapon.Police say during the cha  se, Arian called 911 and claimed he was armed and ready for a shootout.

But as of yet, police have not made the 911 tape public, not even to the family. The lawsuit follows a report that police killings in Los Angeles county have jumped by 70 percent.

Arian's family says they can't help but think the police are trying to cover something up.

Arian's autopsy report shows that he had no drugs or alcohol in his system. Galen says at this point, there's no evidence that police targeted Arian because of his Muslim faith.

However, Galen says if an analysis of the officer's radio traffic proves otherwise, then the entire case will change. The lawsuit filed in federal court also names the city of Los Angeles and LAPD Chief Charlie Beck.

City officials declined to comment on the lawsuit. The family says if the lawsuit is successful they plan to donate a portion of the money back to the city for the purpose of improving officer training.
