"Authorities first learned of Mr. Vongthongthrip's criminal activity when an anonymous caller contacted investigators at the Oregon Humane Society," Special Agent Austin Wallace of the Oregon Humane Society, told Salem-News.com.
The 20-year-old man had no prior arrests and has no history of mental illness. And yet investigators say they found pictures of him posted on the Internet of him sexually abusing his dog, an eight-year-old Red Nose American Pit Bull named Rocky.
