The resident, Shane Smith, 50, was arrested for possession of methamphetamine and lodged in Thayer County Jail. Charges related to child pornography are pending as the investigation continues. Smith is a registered sex offender.

On Friday, investigators executed a search warrant at a residence at 2325 N. Broadwell Avenue #105 in Grand Island. This investigation also began with a cyber-tip received through NCMEC. During the search, investigators found multiple images of child pornography. Michael Taylor, 53, was arrested for possession of child pornography and lodged in Hall County Jail.

NCMEC receives cyber-tips from a variety of tech companies and works closely with the NSP Technical Crimes Division to provide information that can be used to begin investigations.
