RENO, Nevada (AP) — A preliminary hearing has been postponed until next month for a rural Nevada man accused of kidnapping and killing an 18-year-old woman whose body was found last week in a grave in the high desert of the weeks after prosecutors said he abducted her.

Troy Driver’s preliminary hearing scheduled for Tuesday on a kidnapping charge has continued until May 10 as prosecutors continue to prepare an amended criminal complaint formally charging him with the death of Fernley’s Naomi Irion, it has been announced. authorities on Monday.

Driver, 41, of Fallon, has been held in Lyon County Jail in Fernley on $750,000 bail since his March 25 arrest. He was brought before the Canton of Canal Court of Justice last Wednesday for kidnapping.

A preliminary hearing into that charge was scheduled for April 12, with an update scheduled for Tuesday in Fernley Court. But that was before sheriff’s deputies took Driver to jail on suspicion of additional crimes on Friday, including murder with the use of a deadly weapon, robbery, burglary and destruction of evidence.

“Charges are still pending,” Lyon County District Attorney Stephen Rye said in an email Monday to The Associated Press. He said another arraignment or bail hearing could be scheduled after a new complaint is filed.

Wrathion had been missing since March 12, when surveillance video showed a masked man wearing a hoodie getting into his car around 5.25am at a Walmart car park in Fernley, about 30 miles east of Reno.

The Lyon County Sheriff’s Office revealed hours after Driver was arraigned for kidnapping last week that an autopsy confirmed his remains had been found the day before in nearby Churchill County.

On Monday, Judge Lori Matheus approved a joint stipulation signed by Driver’s public defender Mario Walther and Lyon County Assistant Attorney Brian Haslem continuing the proceedings.

It resets the preliminary hearing to May 10, when a new date will also be set for a preliminary hearing to determine if there is enough evidence to tie the case to trial in Lyon County District Court in Yerington.

Walther did not respond to phone calls or emails Monday seeking comment.

Driver has a violent criminal history and served more than a decade in California prison before being released in 2012.
