According to a police report, officers followed a cyber tip that Lenz had uploaded an image of child pornography onto Pinterest.com with an associated email address police were able to link to Lenz.

Under a search warrant, police seized four electronic devices from Lenz’s home. A forensic exam on two of the devices found images of child porn on two of the devices, as well as graphic computer-generated-images and anime images of young females being sexually assaulted with a gun to their heads while being tied and gagged, among other scenarios. Multiple child erotica images were also discovered.

Further forensic exams on the devices continues, according to police.

Lenz told officers he did not load the photo onto Pinterest, but said the email account and Pinterest account were his. He told police he had viewed child porn until about three weeks before his arrest.

Police are suggesting charges of possession of child pornography.
