Gregory Wallen, a convicted sex offender, was ordered to be held without bail. His preliminary hearing is scheduled for July 1.
Wallen was arrested Monday in Pahrump, more than 15 years after the disappearance and slaying of Diana Hernandez. Her body was found in a trash bin near the Sandpiper Apartment complex at Flamingo Road and Maryland Parkway.
Detectives went through a list of registered sex offenders and matched Wallen’s name to the list of volunteers who helped search for Hernandez when she went missing. Police said Wallen’s DNA matched evidence found on the girl’s body.
Wallen had been accused of sexual assault in 1992, but had not been convicted and was not added to the registry until 1999.
