PLANTATION, Fla. -- A retired United States Marine disrupted a robbery in progress when he shot two men who attempted to rob a Subway sandwich shop, fatally wounding one of them, police said.

According to Plantation police, two armed men barged into the Subway at 1949 Pine Island Road shortly after 11 p.m. Wednesday, demanding money from the employee behind the counter. When they tried to force John Lovell into the bathroom, he pulled out a gun and shot both men, police said.

Donicio Arrindell, 22, was shot in the head and later died at the hospital. Fredrick Gadson, 21, was shot in the chest and ran from the Subway, but police found him in hiding in some bushes on the property of a nearby BankAtlantic.

Lovell, 71, was the lone customer at the time. Police said he had a concealed weapons permit.

A witness who was about to enter the Subway at the time said he thought the shootings were justified.

"I think justice, you know, was served and a civilian was a hero for today," Sebastian Shakespeare said.

Police said Lovell, a retired Marine, wouldn't be charged.
