EDMOND — Police "justifiably shot" a naked, unarmed teenager after he was "ineffectively tasered," the city of Edmond claims in response to a civil rights lawsuit filed by the victim's parents.

Edmond's answer, filed Wednesday in Oklahoma City federal court, also contends the actions of the officers "were not based upon and do not differentiate among the races of various citizens."

"Edmond denies that it violated any constitutional rights and denies it is liable to Plaintiffs (in any capacity) for the death of Isaiah Mark Lewis," the city's legal filing stated.

Lewis, 17, was naked and unarmed when police shot and killed him April 29, the legal filing acknowledges. Police said Lewis broke into a home and assaulted officers who had followed him inside and use of a Taser didn't stop him.
