Lincoln County Jail deputies found a 61-year-old inmate dead during breakfast service Tuesday, authorities said.

The inmate, Stewart Douglas Curry of Toledo, had been booked into jail on charges of first-degree rape, first-degree sodomy and first-degree sex abuse.

Police said Curry was a special education assistant at Newport High School who was suspected of having sexual contact with two minors.

Newport police opened a sexual assault investigation in 2015 after Curry was seen leaving a locked storage closet with a 14-year-old girl, according to a news release. Lincoln County Sheriff's Office opened a separate sexual assault case involving a minor in May 2017.

The agencies teamed up and arrested Curry at his home June 20, with help from the U.S. Marshals and the Oregon State Police SWAT team. He was held on $1.5 million bond.

Jail staff performed CPR on Curry and called medics about 5:30 a.m., the sheriff's office said. Medics pronounced Curry dead soon afterward.

Deputies had done routine checks about an hour earlier, the sheriff's office said. Curry was in a cell by himself.

An autopsy is scheduled for July 5.

The Lincoln City Police Department is investigating the death.
