After Nave corrected the truck, police say it hit Quinn's vehicle head-on. Quinn was trapped in the fiery wreckage and died, and his passenger was injured.
Nave was extricated from his vehicle and spent time in the University of Kentucky Medical Center, undergoing a surgery for injuries.
Nave was recently placed on paid suspension after being on unpaid for four weeks, the maximum allowed according to the county's personnel policy.
Wilson said the fiscal court intended to leave him on unpaid until more information about the investigation was received, but the reports were taking longer than anticipated.
Kentucky State Police are still investigating the incident and say the toxicology report on Nave will not be released until the case has been closed.
No charges have been filed against Nave at this point.
