According to the sheriff's office, Taylor's medical condition "is critical but stable."
The driver behind Reynolds witnessed the incident, stopped and rendered aid to Taylor, according to Hamilton County Sheriff’s Capt. Tom Butler.
First responders drove Taylor to the University of Cincinnati Medical Center with serious injuries.
Hamilton County Sheriff Jim Neil said Taylor was awake Friday morning while being prepped for surgery.
"It's going to take him quite a while to recover from the injuries sustained by being hit by a 3,000-pound vehicle," Neil told WCPO.
Authorities found the car Friday morning at the Timber Hollow apartment complex in Fairfield, about six miles away from the scene of the hit-and-run, according to Butler.
He said an anonymous 911 caller reported seeing a car that matched the description of the vehicle from the incident. Investigators found that it also had fresh damage consistent with what happened Thursday night. Police arrested Reynolds at a nearby residence and impounded the vehicle.
The Hamilton County Sheriff's Traffic Safety Unit is investigating the crash.
