TREASURE ISLAND, Fla. (WFLA) — Authorities are searching for a driver who was involved in a deadly hit-and-run crash in Treasure Island on Tuesday night.

The incident occurred just after 8 p.m. Tuesday on 108th Boulevard near Gulf Boulevard.

The Pinellas County Sheriff’s Office said a dark blue pickup truck, possibly a 2016-2018 Chevrolet Silverado, was heading south on Gulf and moved into the left lane to turn onto 108th.

Felicia White, 46, was crossing 108th and was struck by the vehicle. Detectives said White was in a marked crosswalk when she was hit. She died at the scene.

“She was great,” said Kayla Underhill, a friend. “She was a sweetheart. If she could help the world, she would.”

Her friends are now pleading for answers.

“She was in the crosswalk, that’s what makes it so much worse,” said Underhill.

The posted speed limit in the area is 35 mph.

“People speed all of the time around here. It’s ridiculous,” she said.

Deputies said the driver of the pickup fled the scene. They have not been located.

The sheriff’s office is asking those with information about the crash to call detectives at 727-582-6200.

It was just two weeks ago in this same area, where dozens of victims of traffic crashes walked along Gulf Boulevard with the message to slow down.
