A 59-year-old man who authorities say drove a rented car from Arizona to a rural Nevada town and detonated two bombs at the house of former co-workers shot himself dead before the blasts erupted, according to autopsy results made public today.
Glenn Franklin Jones' death was ruled a suicide, Clark County Coroner John Fudenberg told The Associated Press.
Jones' body was blown up in the blasts in Panaca. Fudenberg said the body was identified through fingerprints.
A motive for the bombings hasn't been disclosed, and the findings raise questions for federal, state and local investigators about the type of fuses, timing devices or detonators used to trigger the powerful Wednesday evening blasts.
Lincoln County Sheriff Kerry Lee didn't immediately respond to messages for comment early today.
Lee and neighbors have said residents Tiffany Cluff and two daughters fled from the house before the blast. Husband Joshua Cluff and another daughter weren't home at the time.
Officials said the family of five has been cared-for since the explosions by family and friends. Messages left for the Cluffs by AP haven't been returned.
"I guess he was bent on destruction, but not killing," neighbor Richard Katschke said of Jones, a former nurse who once cared for Katschke's mother at Grover C Dils Medical Center in the neighboring town of Caliente.
Katschke and another neighbor, Dennis Sanders, said Jones knew the Cluff family and helped the Cluffs build the house that was badly damaged.
A hospital administrator confirmed that Jones and the Cluffs worked together as nurses, and that Joshua Cluff was Jones' supervisor.
Lee said Friday that investigators were trying to confirm whether Jones had military experience.
Sanders said Jones told him he'd been an explosives and demolition expert in the Army. Katsche said Jones seemed fascinated with military memorabilia, but didn't say he'd been in the service.
Both described Jones as quiet and courteous, but Sanders said Jones appeared to be struggling to lift himself out of depression following the deaths of his wife and his mother.
Police in the northwest Arizona town of Kingman found several pounds of explosives and improvised bombs in a motorhome where Jones had been living in recent weeks in a recreational vehicle park.
