A man who tried to steal undershirts valued at $16 from a Wal-Mart in Margate, Fla., shot and killed a loss prevention employee there Friday evening, police said.

Lewis Jhon, 49, of Coral Springs, was pronounced dead at North Broward Medical Center after the shooting at about 7:15 p.m., Margate Police Lt. Andy Zettek said

Hollywood resident Terrell Kennith Johnson, 22, was identified as the subject. He fled on foot, and police said they later found what they believed to be his body, which appeared to have a self-inflicted gunshot wound, Zettek said

Johnson was found on the 500 block of NW 51st Avenue, he said.

The incident began when Johnson tried to steal packages of white undershirts at the Wal-Mart at 555 W. Atlantic Blvd in Margate, Zettek said. Jhon detained him, and at some point Johnson shot Jhon near the front entrance of the store, Zettek said.

"Everybody was scared that something was going to happen to them," witness Edward Jorgenson said of when people heard the gunshots in the store.

A woman was also taken into custody but her involvement in the incident is unknown.

After the shooting, police from Sunrise, Margate, Coconut Creek and Plantation converged on the scene, and a helicopter flew in the area searching for the suspect.
