A 59-year-old man who is a former Arapahoe County magistrate was sentenced Monday to 90 days of in-home confinement after pleading guilty earlier this year to sexual exploitation and attempted unlawful sexual contact.

Jeffrey Allan Lane, of Littleton, will serve the sentence as a condition of eight years of sex offender intensive supervised probation and five years of concurrent probation, prosecutors say. He pleaded guilty to the charges in February.

Lane was arrested last year after prosecutors say investigators found a Craigslist posting where Lane was soliciting sex from a 14-year-old boy who could meet him “after school.”

Lane exchanged information with the boy, who was really a sheriff’s office investigator, according to a news release from the 18th Judicial District Attorney’s Office.

“(Lane) confessed that he was indeed the person who was soliciting sex from a minor on Craigslist,” the release said. “(He) acknowledged exchanging sexual messages and a picture with the undercover detective he thought was 14, but stated the conversations were just ‘fantasy.'”
