Overview
- Authorities identified the man as John Buffington, 67, who died by apparent self-inflicted gunshot after troopers arrived at his Princeton home.
- State police say the investigation stemmed from electronic service provider tips routed to the National Center for Missing and Exploited Children, leading the Cyber Crime Unit to obtain a search warrant.
- After entering the residence, investigators reported finding sexually explicit material that included images of at least one child known to Buffington.
- Officials said Buffington worked in Princeton’s after-school program and previously in Lincoln’s LEAP program until 2014.
- A preliminary review shows no apparent evidence that children he encountered were harmed, and authorities provided contacts for the Children’s Advocacy Center of Worcester County (774-317-2132) and the Middlesex Children’s Advocacy Center (781-897-8400).
