LINCOLN, Neb. (AP) — An Omaha man has been sentenced to at least a year in prison after pleading guilty to soliciting sex from an investigator posing online as a 15-year-old girl.

A Lancaster County district judge sentenced 38-year-old David Kucinsky to one to three years in prison. He pleaded guilty to a felony charge of enticing by electronic communication device.

According to court documents, Kucinsky posted an online ad seeking regular contact with a young girl. An investigator with the Nebraska Attorney General’s Office pretended to be a teenage girl and answered the ad.

The two exchanged emails for a month, and authorities say Kucinsky asked for nude photos.
