Police worry about other victims of suspect in 1994 slaying


Law enforcement officials in Las Vegas and Nye County expressed concern Tuesday that a man arrested this week in connection with the 1994 sexual assault and slaying of a 7-year-old girl might have had other victims.

However, neither Las Vegas police nor the Nye County Sheriff’s Office has found any evidence additional children were harmed by 36-year-old Greg Wallen.

Wallen is scheduled for his first court appearance this morning in the slaying of Diana Hernandez.

She was reported missing on April 2, 1994, and was found the next day in a trash bin at the apartment complex where she lived near Flamingo Road and Maryland Parkway.

Las Vegas police arrested Wallen without incident Monday afternoon in Pahrump.

He is held in the Clark County Detention Center without bail on one count of murder and one count of sexual assault of a minor under the age of 14.

Wallen served several years in a Nevada prison after being convicted of lewdness with a minor stemming from a 1992 incident involving a 4-year-old girl in Nye County.

“This is twice now for him,” homicide Lt. Lew Roberts said. “Who’s to say there is not more?”

Nye County Sheriff Tony DeMeo expressed a similar sentiment.

“Any community would be concerned with something like this, especially considering the violence that took place and the age of the victim,” DeMeo said, referring to the Hernandez case.

An autopsy report revealed that Hernandez also was suffocated and beaten on the head.

Las Vegas police linked Wallen to the slaying through DNA samples retrieved from Diana’s body and a partial fingerprint found on the cardboard box where her body was found.

DeMeo said his department’s arrest records show Wallen has had several scrapes with the law since 2003.

Some of those incidents include a domestic violence charge, obtaining money under false pretenses, and failing to register twice as a sex offender in 2006.

The police report said Wallen has been required to register as a sex offender since 1999.

Anyone with information in Clark County is asked to contact the Las Vegas homicide Section at 828-3521 or Crime Stoppers at 385-5555. Anyone in Nye County with information can call the sheriff’s detective unit at 775-751-7000.
