Enumclaw Horse Sex Case

The Enumclaw horse sex case was a 2005 incident in which Kenneth Pinyan (June 22, 1960 – July 2, 2005), an American Boeing engineer residing in Gig Harbor, died from injuries received during anal sex with a stallion at a farm in an unincorporated area in King County, Washington, near the city of Enumclaw. He had videotaped previous sex acts with the horses and distributed them informally under the name Mr. Hands.

During a July 2005 sex act, videotaped by a friend, he suffered a perforated colon and later died of his injuries. The story was reported in The Seattle Times and was one of that paper's most read stories of 2005. It was informally referred to as the "Enumclaw horse sex case".

Pinyan's death rapidly prompted the passing of a bill in Washington prohibiting both sex with animals and the videotaping of the same. Under current Washington law, bestiality is now a Class C felony punishable by up to five years in prison.

A documentary of the life and death of Pinyan, and the life led by those who came to the farm near Enumclaw, debuted at the Sundance Film Festival 2007 under the title Zoo. It was one of 16 winners out of 856 candidates for the festival, and played at numerous regional festivals in the United States thereafter. Following Sundance, it was also selected as one of the top five American films to be presented at the prestigious Directors Fortnight sidebar at the 2007 Cannes Film Festival.
