GARLAND (CBSDFW.COM) – A Dallas County Deputy Constable shot and injured a 17-year-old suspect who lunged toward him with a knife Tuesday night, a spokesman said.

According to Garland Police Department spokesman Joe Harn, a deputy was driving his squad car in the 3600 block of Leon Road at about 8 p.m. Tuesday when Zechariah Way, 17, ran out in front of the vehicle holding a knife.

The officer got out of the car and ordered Way to drop the weapon and called for backup, Harn said. The suspect then sprinted into a nearby wooded area and the deputy chased him.

When more police arrived, Way “continued to confront deputies and would not drop his knife.”

Harn said he “moved toward one of the deputies in a threatening” manner and was shot by a six-year veteran deputy constable. It wasn’t clear whether the deputy who fired the gun was the same deputy who initially ordered Way to drop the knife.

Way was charged with two counts of aggravated assault on a peace officer and was taken to Baylor Hospital of Dallas. He is expected to survive his injuries.

The deputy was placed on routine administrative leave pending a Garland Police Department investigation, Harn said. His name was not released.
