Florida Highway Patrol is looking for a hit-and-run suspect after a motorist struck and killed a Jacksonville pedestrian early Saturday.

Jacksonville resident Marvin L. Corley, 41, was struck and killed by an unknown vehicle at about 6 a.m. Saturday.

The vehicle was traveling west on U.S. 90 (West Beaver Street) and approaching Wheeler Avenue. Corley was walking east on the westbound outside shoulder of U.S. 90 toward Watershed Drive. For unknown reasons, the motorist traveled off the road to the right, causing the right front end of the vehicle to strike Corley, a news release said.

The motorist then fled in an unknown direction.

Hannah Fisher, Corley's girlfriend of six years, says she believes she was the last person to see him.

"He came to my job around 3, 3:30 in the morning, said he had run out of gas up the road," Fisher said.

Fisher said he put a few dollars of gas in a can and walked away. She says he never came back.

"I thought he was upset that I was upset, so I just went home," Fisher said.

Fisher said Corley was supposed to start a new job that morning, but never came home.

"My dad saw on the news that there was an unidentified man on the side of the road," Fisher said.

Fearing the worst, she went to the scene. After speaking with FHP, she realized Corley was the unidentified man.

"I lost it," Fisher said. "They just left him there, you know?"

Fisher says that is a notoriously bad road for pedestrians, especially at night.

"There's no sidewalks, it's dark, it's always dark," Fisher said.

According to Florida's Integrated Report Exchange System, there have already been 193 pedestrian crashes this year, 18 of which were fatal.

"I just don't know how many people it's going to take for them to do something," Fisher said.

Fisher described Corley as a loving man.

"He loved everybody, he loved kids, he did anything for anybody, no matter what it was," Fisher said.

FHP currently does not know the make and model of the vehicle that hit Corley but says it may be a red/maroon vehicle with a red tail lens missing and/or damage on the right side.

An investigation is ongoing.
