CHARLOTTE, N.C. -- A maker of electronic stun guns is being sued by the family of a Charlotte teen killed after he was shocked with one of the weapons.

The lawsuit was filed Tuesday in federal court and doesn't list a specific monetary amount. It says Taser International didn't warn its customers that the weapon could be lethal if deployed near the chest.

Seventeen-year-old Darryl Wayne Turner died of cardiac arrest in March 2008 after a confrontation with police at the Food Lion where Turner had worked. Turner was involved in an argument with his managers and when police arrived, he knocked a display off the counter. The officer then shot Turner in the chest with a Taser.

Police said the officer held the trigger down for 37 seconds, instead of the recommended five.

The lawsuit says Turner's death could have been prevented if Taser International trained police departments to properly use the devices and keep defibrillators nearby.

The city of Charlotte paid $625,000 to Turner's family last August, although the city didn't admit wrongdoing.

A spokesman for Taser International said the Arizona-based company doesn't comment on pending litigation, but stands behind the safety of its products.
