A Cherry Hill man will spend 15 years in prison for traveling to Pennsylvania to have sex with a minor, plus manufacturing and possessing child pornography, the FBI announced Tuesday.

Jon J. Lackner, 48, was convicted in June 2011 of traveling across state borders with the intent of having sex with a minor. A jury determined that Lackner used his computer, a Web camera, the Internet, mail and a cell phone to attempt to induce a minor to engage in illegal sexual activity, and that he attempted to transfer obscene materials of him to the minor.

The crimes took place between August 2008 and March 2009.

Lackner also pleaded guilty Tuesday to two more counts of manufacturing and possessing child pornography, stemming from a 2007 incident in which he used a minor to produce visual depictions of sexually explicit conduct, the FBI said.

U.S. District Court Judge Petrese Tucker ordered Lackner to complete five years of supervised release after his prison term, plus pay $1,500 in fines and $500 for a special assessment.

Lackner was a practicing dentist in Vineland and arrested at his office there in 2009.
