Not even carousel riders at the old-fashioned amusement park were safe from the licentious eye of Glenn M. Blank's video camera, according to police in Locust Township, Columbia County.

And despite Blank's 1999 conviction, he wasn't registered on the state's Megan's Law Web site.

Blank, 55, of Oak Avenue near Woodland, in Sharon Hill, was caught June 19 following a 13-year-old girl from a park restaurant to a bench, all the while filming up the girl's skirt without her knowledge, the affidavit said.

A security officer spotted Blank, who subsequently gave the officer permission to view his camera footage.

Police said that the tape included shots of the girl's nude buttocks and footage of the crotch areas of juveniles and adults on the park's Grand Carousel.

Built in 1926, Knoebels Amusement Resort in Elysburg bills itself as "America's Largest Free-Admission Park." Just one month ago, Inquirer readers voted it the third-best "one tank away" vacation destination.

On June 19, it was also Blank's destination, and the place where he allegedly took his obsession of children to the next level.

In 1998, Blank and his brother, Donald, were arrested after a search of the Sharon Hill home they shared with their mother revealed that Glenn and Donald Blank were in possession of an "incredible volume" of child pornography, said Delaware County Deputy District Attorney Michael Galantino, the prosecutor who handled the case.

Police searched the home after Donald Blank was caught filming a little boy inside of a men's room at the Strasburg Rail Road in Lancaster, Galantino said.

"The combined total evidence Donald and Glenn Blank were in possession of filled the back of a tractor-trailer at the state police barracks," he said.

The pornography included photographs, magazines and videotapes, all of which appeared to be made commercially overseas, Galantino said. Although Donald Blank favored young boys, most of the images in Glenn Blank's possession were of girls younger than 13, including some as young as 3 or 4, he said.

"It was bad enough he was collecting images that were created by other people," Galantino said. "But if he's now going into private places and videotaping victims, that makes it so much worse."

After being convicted in 1999, Donald Blank was sentenced to two to five years in state prison followed by eight years state parole, which is scheduled to end next year.

Glenn Blank was sentenced to 11 to 23 months in county prison and seven years probation, which he was scheduled to complete in October 2007. In 2000, Glenn Blank violated his probation, but Galantino said that he was unsure of the nature of the violation or if it had affected Blank's probationary time.

Neither of the men is registered on the state's Megan's Law Web site, which requires lifetime registration for sex offenders.

A trooper at the state police's Megan's Law division said that it appeared that police never received the brothers' information, but that the department would "certainly look into it."

Galantino said that there was a period in the late '90s and early 2000s when Delaware County judges found Megan's Law to be unconstitutional, which he said was not unusual at the time. But Galantino was "just about certain" that the Blanks would have had to register once the county began following the law.

Glenn Blank is scheduled for a preliminary hearing in Columbia County today on charges of sexual abuse of children, invasion of privacy, stalking and disorderly conduct. Blank has has been held in Columbia County Prison on $25,000 bail since his arrest. *
