After an administrative hearing Monday, Memphis Police Officer Terrance Shaw, who shot a killed a teen in a September 2012 encounter, resigned from the police force, Director Toney Armstrong said.
Shaw resigned from the police force in lieu of termination.
Director Armstrong said Shaw was facing two administrative charges of personal conduct and discharging a firearm.
Shaw fatally shot 15-year-old Justin Thompson Sept. 24, 2012, near the Parkway Village area of Memphis. Shaw was off duty at the time. He told investigators he was defending himself from a robbery when he shot and killed Justin.
Police commanders questioned why Shaw was with the teen in the first place.
Director Armstrong said Shaw should not have put himself in a position where he was alone with the 15-year-old.
"As long as this case went on I think there are several questions that we had at the inception of it, and there's still several," Director Armstrong said. "We don't feel like that as a police officer he should have allowed himself to be put in that position."
The Shelby County District Attorney decided not to press charges against Shaw following a lengthy probe into the incident by the Tennessee Bureau of Investigation. The TBI concluded their investigation in December, but the case file was sealed.
Shaw was also the subject of an internal police investigation.
Director Armstrong wouldn't discuss the relationship between Shaw and Justin, only saying there are still many questions surrounding the case.
"You look at this young man who lost his life during this," the police director said. "He was 15-years-old. So, regardless of the fact, we don't feel that it's conduct becoming of a police officer to have an interaction with a minor child without the consent of that child's parent."
The officer-involved shooting inflamed the community and in its wake ultimately led to a review of the Memphis Police Department.
The police director planned on calling Justin's mother to explain to her that Shaw no longer wears a police badge.
"There are no winners, there are no winners in this whole ordeal and certainly my heart goes out to (Mrs. Thompson)," Director Armstrong said. "I'll be reaching out to her shortly and having a conversation with her and I explained that to her."
In February when it was revealed the DA would not press charges against Shaw, Shirley Thompson, Justin's mother, planned to hire an attorney to investigate her son's killing.
