A 64-year-old Bushkill Township man was jailed Tuesday morning in lieu of $500,000 bail on charges he sexually assaulted preteen children and filmed some of his attacks, township police report in court papers.

Gary E. Adamczyk, of the 200 block of Filetown Road, faces two identical sets of eight charges, including aggravated indecent assault of a child and possessing child pornography, court records show. All 16 charges are felonies.

The abuse went on for three years, police said.

After one of the children reported the assaults to township police on July 30, a search warrant was served at the home, police said. Investigators found a Canon Rebel XSi camera where a child said it would be, police said.

Investigators also recovered a Dell Dimension 3000 computer which the Petzold Digital Forensics Laboratory determined contained 23 videos and 69 images, at least some of which separately included the children in the nude and at times showed Adamczyk assaulting one of them, police said. The lab was able to determine at least some of the videos and images were recorded on a Canon Rebel XSi, police said.

Adamczyk was arraigned at 11:30 a.m. before District Judge Douglas Schlegel. Adamczyk’s preliminary hearing is tentatively scheduled 9 a.m. Dec. 9 in Schlegel’s court in Wind Gap.

Court papers did not list an attorney for Adamczyk.
