A registered nurse accused of engaging in sex acts with a teen boy was found dead the same day he was to be arraigned in court on three felony charges.

Randolph Calvin Tipper, 57, was scheduled to be arraigned April 25 in connection with charges he sodomized a 14-year-old boy two years ago. He didn't show, and a human resources employee at Kern Medical Center -- where Tipper was employed -- told the judge Tipper had died.

Paul Hensler, CEO of KMC, said Wednesday that Tipper's roommate discovered his body that morning. Hensler said nothing is official until the coroner's office completes its investigation, but there's a strong possibility Tipper died of natural causes.

Hensler said he didn't know Tipper well, but he was very popular among the staff and patients.

"He was regarded as a very caring, very good person," Hensler said.

Tipper worked at KMC from June 19, 2010 until his death. Hensler said police called him April 22 to inform him they'd arrested Tipper the Friday before, and they told him about the alleged crimes.

Hensler said Tipper was working as interim director of home care, a management position, and didn't have contact with patients. The CEO said Tipper was allowed to continue working in that capacity as there were only allegations to go on at the time and no patients were at risk.

A probable cause declaration filed in court by Bakersfield police said the victim came forward in April to report that Tipper, a neighbor, had asked him to take care of his dog in late December 2011. The victim told police that Tipper gave him several shots of whiskey and then took advantage of him.

Police spokeswoman Michaela Beard said there aren't any other known victims but the investigation is ongoing. A detective has been assigned to investigate the circumstances of Tipper's death.
