A previous Beaver County resident, classified as a sexually violent predator, is facing multiple felony charges after authorities allege he failed to update his address and other required information under Megan’s Law.

David F. Slack, 67, was charged Friday with two first-degree counts of failure to provide accurate registration information and two second-degree counts of failure to register with the Pennsylvania State Police and failure to verify address. Bail was set at $50,000 by Magisterial District Judge Laura Bauer.

According to the Affidavit of Probable Cause, Conewango Township police investigated an anonymous report for a violation of Megan’s Law occurring at the defendant’s address. Police had allegedly received prior information from Warren County Human Services also regarding the defendant.

According to the affidavit, the officer then used public records and law enforcement databases to determine Slack’s last registered address. The last in-person registration was allegedly completed with the Pennsylvania State Police on April 14, 2025, for an address in Beaver.

According to the affidavit, Slack is classified as a sexually violent predator in database records. Slack is allegedly required to comply with quarterly in-person verification and photograph updates, and must also report changes in residence, phone number and other required information to the Pennsylvania State Police within three business days. Slack allegedly signed registration paperwork stating that he understood these requirements.

According to the Affidavit, Conewango Township police spoke with Warren County Human Services, who said Slack moved during the week of October 13, 2025. It was allegedly stated that Slack’s provided phone number was also not reported to the Pennsylvania State Police.

According to the affidavit, Slack failed to notify the Pennsylvania State Police of changes in residence and phone number within the required time period. Slack also allegedly failed to complete quarterly in-person verification, violating Megan’s Law requirements.

According to the Affidavit, Warren County Human Services had previously warned Slate that he was in violation of these requirements, and he failed to contact the Pennsylvania State Police to update his address and phone number.

“Based on the above investigation, I have probable cause to believe that David Frank Slack knowingly failed to comply with Pennsylvania Megan’s Law registration requirements,” the officer stated in the affidavit.
