Timothy Gordon, 39, is in critical condition after being hit while driving his moped on the Orange Avenue bridge in Daytona Beach.
Fox 35 talked to his sister Bettie, "It makes me really upset because how could you just hit someone on a bridge or anywhere and not stop and help them at least call the police."
Police released video of the suspect's white Kia Soul. They say the driver never stopped after hitting Gordon.
"At least they know what kind of car it was, so it should be soon that they find out." The hit and run happened at 5:30am. "Do you know where he was going this morning? He was actually on his way back to his girlfriend's house."
Police say the accident happened at the crest of the bridge. Investigators say it was so bad, that part of the suspect's car was imbedded in the victim's scooter.
"There's blood and bleeding on both sides of the brain. They're hoping tomorrow if the swelling goes down, they won't have to do brain surgery. It's all depending on the first 24 hours." Bettie says her brother used his scooter to go to class every day. "He's working on his second bachelor's degree. He's fun, he's outgoing. He gets around everywhere, knows a lot of people."
She has a message to the driver who left Timothy lying on the bridge with severe head injuries and broken ribs. "If you could please turn yourself in. Say something, let us know what happened. Hopefully he'll be ok. But if he doesn't we want to know."
Anyone with information should call the Daytona Beach Police Department at 386-671-5100.
