An 18-year-old man was shot and fatally wounded in south St. Petersburg on Sunday night after getting into an altercation with another person, police said.

Jerrod Evans was shot in the upper torso outside Johnie's Food Mart, 1404 16th Street S., around 8:40 p.m., police said. He was taken to Bayfront Health St. Petersburg, where he died a short time later.

Police early Monday arrested Darzaughn Williams, 18, and charged him with being an accessory after the fact to second degree murder. Investigators say Williams was driving the car from which the shots were fired.

The shooter is still being sought, police said.
