Tigard man sentenced for sexually exploiting 7 girls via social media
A 50-year-old Tigard man was sentenced today to 180 months in federal prison and lifetime supervised release after finding, contacting, grooming and sexually exploiting seven minor girls ages 13-to-17 using a variety of social media platforms.
The sentencing David Earnest Otto was announced by the U.S. Attorney's Office for the District of Oregon.
According to court documents, on November 20, 2016, the mother of one of Otto's minor victims contacted the Sonora Police Department in Sonora, California to report that her fifteen-year-old daughter had been communicating on Instagram with an unknown adult male.
An analysis of the victim's chat log revealed that she had engaged in highly sexual conversations with another Instagram user and, when prompted, sent the user nude photos of herself. Investigators linked the subject's Instagram account to Otto using the IP address of his home in Tigard.
Following execution of a search warrant at the Tigard residence, investigators analyzed the data on Otto's seized digital devices and discovered six additional minor victims located around the country.Â
FBI agents, in cooperation with local officials, then sought to locate and interview the victims.Â The victims described similar crimes, in which Otto contacted them on social media or via the internet and, having built rapport with them, directed them to produce and send him images and videos of child pornography.
On February 6, 2018, Otto pleaded guilty to one count of production of child pornography.
This case was investigated by FBI Portland's Child Exploitation Task Force (CETF) and Sonora Police Department and was prosecuted by the U.S. Attorney's Office for the District of Oregon.
FBI Portland CETF conducts sexual exploitation investigations—many of them undercover—in coordination with other federal, state, and local law enforcement agencies.
