The former owner of a South Jersey roller skating rink has been sentenced to six years for sexually assaulting a child and showing the child pornography on a laptop at the skating center.

Jon J. Carlo, 50, of Franklinville, was convicted in February on second-degree charges of sexual assault and endangering the welfare of a child/filming a child in a sex act, along with third-degree counts of showing obscene material to a child, invasion of privacy and endangering.

The investigation into Carlo began in August 2015 when he was accused of showing pornography to a minor on a laptop at Franklin Skating Center on Delsea Drive in Franklin Township. Carlo owned the rink at the time. From there, investigators searched his home and business, ultimately charging him with crimes dating back to 2014.

Carlo sexually assaulted a child under the age of 13 in November 2014, and that same month made a video recording when a child’s “intimate parts were exposed without consent and under circumstances in which a reasonable person would not expect to be observed,” prosecutors said.

The victim was a frequent patron at the skating rink and Carlo was able to strike up a friendly relationship that allowed him to commit his crimes, prosecutors said.

Only one victim was identified as part of the investigation, but authorities said they suspected there were others who didn’t step forward. All of the crimes occurred at the skating rink.

Superior Court Judge M. Christine Allen-Jackson sentenced Carlo to six years on the sexual assault charge, with a requirement that he serve 85 percent of that term before he is eligible for parole. He was sentenced to a concurrent six-year term on the second-degree endangering charge and concurrent four-year terms for the third-degree charges of endangering, invasion of privacy and showing obscene material to a child.

He must also register as a sex offender and is subject to parole supervision for life.

Carlo still faces prosecution in another case.

Following his arrest, a court-approved sex offense restraining order was issued in 2015, prohibiting him from unsupervised contact with any minors.

Two years later, though, he was accused of violating that order when he allegedly showed pornographic photos on his phone to a minor. He was indicted in July 2017 on a third-degree charge of endangering the welfare of a child and fourth-degree contempt for violating the restraining order. That case is ongoing.
