Tiffany Powell told police that her family and her pastor had advised her to surrender, Richmond police Lt. Mark Gagan said today.
She turned herself in at the police station at about 10:30 p.m. and was arrested on suspicion of felony hit-and-run and vehicular manslaughter in connection with the death of 49-year-old Laura Casey.
Casey had been riding her bicycle on Carlson Boulevard at Ohio Avenue at about 6 p.m. Saturday when a white four-door sedan struck her and knocked her off her bicycle, police said.
Witnesses said the driver, believed to be Powell, paused momentarily before fleeing.
Casey was on the ground and calling for help when the second vehicle struck and killed her, according to police.
Police still have not identified the second driver, Gagan said.
Casey's family held a press conference Monday pleading for witnesses or suspects to come forward.
Witnesses are asked to call the Richmond Police Department at (510) 233-1214 or Officer Ramon Middleton at (510) 621-1583.
The Police Department is also offering a $10,000 reward for any information leading to the arrest and conviction of the hit-and-run drivers, Lt. Enos Johnson said.
