Nashville, Tenn. (WDEF)- Former Chattanooga bus driver Johnthony Walker appeared in a preliminary hearing today in Nashville.
The 25-year-old faces a single charge of aggravated statutory rape.
His case was bound over to the grand jury.
Walker admitted to having consensual sex with a 14-year-old girl while he was staying in Nashville, according to Davidson County authorities.
Earlier this year Walker was convicted of six counts of negligent vehicular homicide after a bus he was driving crashed, killing six children from Woodmore Elementary School in Chattanooga.
A Hamilton County judge sentenced Walker to four years in prison, but Walker was allowed to remain outside custody during the appeals process after making a $50,000 bond.
Walker was staying with the 14-year-old victims family in Nashville when the accused rape occurred.
Walker has since been held in the Davidson County Jail.
