A Phoenix Police Department sting operation led to the arrest, conviction and sentencing of a 36-year-old man for child sex trafficking, the Maricopa County Attorney's Office announced.

Adan Ivan Munoz Espinoza has been sentenced to seven years in prison in the case.

In January, Phoenix police began an undercover investigation in which a detective went online posing as a 16-year-old girl.

Espinoza invited the “girl” to engage in sex with him and offered $80 for the act. He made arrangements to meet the “child” at a nearby store, according to a release.

 Espinoza had with him at the time of his arrest the cell phone he used to contact the undercover detective posing as the girl, the release stated.

A jury last month found Espinoza guilty of one count of child sex trafficking. Upon release, he will be required to register as a sex offender.
