Two felony charges filed against an area man in Warren County have been withdrawn.

David F. Slack, 67, was charged Feb. 20 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 online court docket information, Slack is still in the Warren County Prison. He is due back in court in June.

During his recent arraignment in the Court of Common Pleas in front of Judge Todd Woodin, the charges of failure to provide accurate registration information and failure to verify address/be photographed were withdrawn.

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 Slack. 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 Slack 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.

Slack was found guilty in 2025 after a one-day trial of unlawful contact with minor – sexual offenses; indecent assault – without consent; indecent assault – person unconscious; indecent assault – victim less than 13 years of age; and indecent assault – victim less than 16 years of age and defendant four or more years older. The jury found beyond a reasonable doubt that Slack had inappropriately touched a sleeping nine-year-old girl “to satisfy his sexual desires.”

Slack was sentenced in 2016 to 20 to 54 months in state prison as well as status as a Tier 3 sex offender and sexually violent predator under the state’s sex offender registration laws, which means As a Tier III sex offender and sexually violent predator is to constantly update his pertinent information to police for the rest of his life.
