RANCHO CUCAMONGA – An Ontario police officer was arrested last week for having sex with a 17-year-old girl.
Tyler Duane Stone, 30, of Rancho Cucamonga, has since resigned his position with the Ontario Police Department, according to officials. On November 8, 2014, investigators became aware that Stone was having an inappropriate relationship with a female under 18-years-old. One month later, Ontario police requested San Bernardino County Sheriff’s investigators to take over the case.
Detective John Everman and Sgt. Dana Foster, part of the Sheriff’s Department Crimes Against Children Detail, began piecing together information, determining that Stone had met with the teenager while he was on duty, later developing a sexual relationship with her.
The sexual acts, they said, took place in Ontario and at Stone’s residence in the neighboring city of Rancho Cucamonga. Stone resigned from Ontario PD on December 22.
Last week, the county District Attorney’s office issued a warrant for Stone’s arrest. The warrant specified two counts of oral copulation of a minor, one count of unlawful sex with a minor and one count of annoying or molesting a child. Investigators said that Stone turned himself in on February 19.
He was booked at the West Valley Detention Center, his bail set at $150,000. Officials said that Stone posted bail and released at 3:25 a.m. the next day. Before resigning, Stone worked for Ontario police for less than four years.
