Investigators received a tip from the National Center of Missing and Exploited Children that child pornography files were found on a Snapchat account associated with York's email address and phone number. The IP address that was being used to access the account was later traced to York's home in Lunenburg, according to a statement of facts. Lunenburg police obtained a search warrant and allegedly found child sexual abuse material on York's account.
The NCMEC's CyberTipline is a Congressionally authorized clearinghouse for reporting child sexual abuse material (CSAM) and other forms of child exploitation. Companies are required by law to report apparent child exploitation to the CyberTipline. When a company sends a report, NCMEC reviews it and then forwards it to the appropriate law enforcement agency for investigation. Statistics related to NCMEC reports can be nuanced.
