Amanda Jean Snell was a 20-year-old Navy petty officer found dead in her barracks room at Joint Base Myer-Henderson Hall in Arlington, Virginia. Her supervisor discovered her body inside a wall locker on July 13, 2009, after she failed to report for duty.

Investigators later focused on a fellow service member, 25-year-old Jorge Avila Torrez, a former U.S. Marine corporal who lived a few doors down on the same deck. Court testimony says Torrez confessed to a fellow inmate that he entered Snell’s unlocked room while she slept, bound her wrists with her laptop power cord, and strangled her with it before hiding her body in the wall locker. Prosecutors presented internet history they described as evidence of sexually motivated fantasies.

A jury convicted Torrez of first-degree murder in April 2014 and, after hearing evidence about his prior violent crimes, sentenced him to death for the premeditated killing.
