LINCOLN, Neb. (AP) — A 32-year-old man has been sentenced to 18 to 30 years in prison for exchanging money for sex with minors in Lincoln.

Adam Brunswick was sentenced Tuesday. According to prosecutors, Brunswick met two girls, who were 14 and 15 at the time, on a social networking website in 2013. Authorities say they agreed to meet at Ballard Park, where he engaged in a sex act with each of them.

According to prosecutors, Brunswick sent text and instant messages to the girls for several months, offering money for sexual acts. Police say one of the girls eventually told her mother what was happening.

Brunswick was given two terms of nine to 15 years in prison that he will serve consecutively.
