The man accused of fatally shooting one man and wounding two women at Vancouver’s Smith Tower Apartments in October died Tuesday, according to the Clark County Sheriff’s Office.

Robert “Bob” Breck, 80, had been in custody at the Clark County Jail since Oct. 3 and was being held without bail. He was hospitalized on Feb. 5 after falling ill, and he died of natural causes, the sheriff’s office announced Wednesday. Breck’s family was aware of his condition.

He was facing one count of first-degree murder and two counts of attempted first-degree murder in Clark County Superior Court. His trial was scheduled for April 11.

Breck was arrested Oct. 3 after a nearly 2½-hour standoff with law enforcement at the senior living apartments after firing shots in the building’s lobby that killed fellow resident Dean Leon Tunstall, 75, and wounded fellow resident Enelia Montoya, 73, and her caregiver, Shawna L. Garris, 44, according to police.

The Clark County medical examiner determined that Tunstall died of gunshot wounds to the chest from a revolver.
