MANNING, Ore. (KOIN) -- DNA on a hat led authorities to arrest a man suspected of sexually abusing a gelding horse for eight months.
Antonio "Tony" Hall-Rivas, 47, was arrested by the Washington County Sheriff's Office Wednesday afternoon at his home on Northwest Sunset Highway in Manning, Ore.
Deputies believe Hall-Rivas trespassed into a barn and abused the horse multiple times beginning in September 2012.
The Washington County Sheriff's Office reports they've been following this case since October 2012, after which the "abuser became bolder, with more frequency."
In the end, detectives found "various items of evidence left in the barn and along the suspect's escape path," according to a news release sent to KOIN 6 News. "Detectives were able to obtain a hat that they submitted to the Oregon State Police Crime Lab for possible DNA analysis. On April 9, 2013, detectives received a positive match from the DNA on the hat. They identified Tony Hall-Rivas as the suspect."
Hall-Rivas was arrested around 4 p.m. Wednesday. He was taken to the Washington County Jail, where he faces charges of five counts of Trespassing, five counts of Second Degree Burglary, and eight counts of Sexual Abuse of an Animal. He is being held on $20,000 bail.
