CHARLOTTE - A 17-year-old died at Carolinas Medical Center on Thursday after a Charlotte-Mecklenburg police officer shocked him with a Taser during a confrontation at a grocery store in northeast Charlotte.

An autopsy will determine how Darryl Wayne Turner died.

Turner had worked as a cashier and bagged groceries at the Food Lion at 3024 Prosperity Church Road, where the incident happened.

Officers responded to a disturbance call at the grocery store about 1:15 p.m. When they arrived, they saw Turner throwing something at a store manager, according to a CMPD news release issued Thursday night. The release does not say what the object was, and a police spokeswoman could not be reached.

According to the release, Turner appeared to be agitated, refused all commands and advanced toward the police officer. The officer then used his Taser to get Turner under control, the release said.

The release does not say whether Turner was armed.

Turner's mother, Tammy Fontenot, said she couldn't see her son throwing something at someone during an argument.

"He had manners," she said. "But he did have a temper."

A preliminary check of N.C. criminal records did not turn up any criminal convictions for the teen.

Turner graduated from Crossroads Charter High School last year, his mother said. He had wanted to go to Central Piedmont Community College and be a personal trainer. He didn't have any health problems and had never been in trouble, she said.

Except on Thursday.

Around lunchtime, Turner had come home to eat and told his mom that he had stolen a couple of Hot Pockets from the store. A supervisor planned to get a district manager involved and he feared disciplinary action, she said.

She said she told him to go back to the store and face up to what happened.

It wasn't long after lunch she got a call from one of her son's co-workers, who told her about the incident, she said.

After Turner was hit, police called the Charlotte Fire Department and paramedics, department policy anytime an officer uses a Taser gun, the release said.

Homicide detectives are investigating Turner's death and will present their findings to the district attorney, the news release said.

The Police Department also will conduct its own investigation into the incident. A review board, made up of the officer's chain of command, internal affairs and a member of the city's community relations committee, will review evidence and interview witnesses to determine whether the officer followed all the department's policies, the news release said.

Charlotte-Mecklenburg police have used Tasers or similar weapons since 2004 and said in their release that they have had no deaths associated with their use. Last year, officers used Tasers 138 times. Officers are to use them to prevent, whenever possible, the escalation to the use of deadly force.
