LAS VEGAS — Authorities say a 44-year-old Nevada prison inmate has died at a Las Vegas hospital, days after he was found unconscious with a bed sheet around his neck in his cell in Ely.
The Clark County coroner said Thursday that William Ellis Jenckes Jr. was pronounced dead early Tuesday at University Medical Center. A cause of death is pending the results of blood toxicology tests.
State prisons spokesman Steve Suwe (SOO-ee) says Jenckes was found alone in his cell Jan. 15 and taken to a hospital in Ely before he was flown by medical helicopter about 250 miles to Las Vegas.
Jenckes was serving 20 years to life in prison on a murder with deadly weapon conviction in Clark County. He had been sentenced in December 1985.
