Emilio Luna

An Arizona pediatrician who was once the subject of an FBI manhunt was sentenced to federal prison Monday. He evaded capture for nearly four years.

Emilio Luna was sentenced to 14 years and a lifetime of supervised release after pleading guilty to two counts of distribution of child pornography.

He must also register as a sex offender and is banned from working as a pediatrician.

Luna made national headlines in September 2010 when he cut off his electronic-monitoring device and left it in a Glendale parking lot.

At one point, Luna was on the FBI's cyber-crimes most wanted list and there was a $20,000 reward for information leading to his arrest.

He turned himself in to authorities last year in Nogales.
