Kenneth Pinyan

Pinyan, Tait, and a third unidentified man snuck into the barn of the Southeast 444th Street farm that night.

Either Pinyan or the unidentified man recorded Tait being anally penetrated by a stallion the men had referred to as "Big Dick".

After finishing, Tait then filmed Pinyan being anally penetrated by the same horse.

During this incident, Pinyan sustained internal injuries including a perforated colon.

In the 1970s, many statutes that had criminalized certain sex acts in various U.S. states were repealed, largely since they had criminalized some consensual sex acts between adults that were no longer considered appropriate to forbid (e.g., criminalizing all oral and anal sex).

An effect of the repeal was that bestiality became legal in the state of Washington.

Kenneth Pinyan had worked for Boeing for eight years.

He had previously been married to a woman and had children with her.

He had moved from Seattle to Oak Harbor, Washington.

Pinyan had been building a new house and a barn that he planned to keep a horse in, along the Key Peninsula Highway in Gig Harbor, Washington.

He was about to begin making payments on the property's mortgage.

Pinyan had previously lost the ability to experience certain sensations after a motorcycle accident, and he had begun to seek out increasingly extreme sexual acts such as insertion of extremely large dildos, fisting, and receptive anal sex with horses.

In Washington state, a law was repealed on July 1, 1976, that had said:

"Every person who shall carnally know in any manner any animal or bird, or who shall carnally know any male or female person by the anus or with the mouth or tongue; or who shall voluntarily submit to such knowledge; or who shall attempt sexual intercourse with a dead body, shall be guilty of sodomy..."

In the early 2000s, he found a group of men online, nicknamed "zoos", who began meeting at a farm in an unincorporated area of King County, Washington, for communal weekends.

The group filmed one another being anally penetrated by horses and sometimes engaged in sex with each other afterwards (which was also filmed), and posted the videos online.

The Enumclaw horse sex case was a series of incidents in 2005 involving Kenneth D. Pinyan, an engineer who worked for Boeing and resided in Gig Harbor, Washington; James Michael Tait, a truck driver; Douglas Spink; and other unidentified men.

Pinyan and Tait filmed and distributed zoophilic pornography of Pinyan receiving anal sex from a stallion under the alias "Mr. Hands".

After engaging in this activity on multiple occasions over an unknown span of time, Pinyan received fatal internal injuries in one such incident.

The story was reported in The Seattle Times and was one of that paper's most read stories of 2005.

Pinyan's death rapidly prompted the enactment of a bill by the Washington State Legislature that prohibits both sex with animals and the videotaping of such an act.

Under current Washington law, bestiality is now a Class C felony punishable by up to five years in prison.

As bestiality was legal in Washington state at the time, Tait was instead convicted of trespassing and was sentenced to a one-year suspended sentence.

On July 2, 2005, Douglas Spink dropped Pinyan off at the Enumclaw Community Hospital.

Medical staff wheeled Pinyan into an examination room before realizing he was dead.

According to the Medical Examiner's Office, Pinyan, 45, "died of acute peritonitis due to perforation of the colon", and the death was ruled accidental.

After Pinyan died, the authorities used his driver's license to find acquaintances and relatives.

Earlier news reports stated that the authorities had used surveillance camera footage to track down Pinyan's companion.

Using the contacts, the authorities found the farm where the incident occurred.

The police tracked down the rural Enumclaw-area farm, which was known in zoophile chat rooms as a destination for people wanting to have sex with livestock, and seized 100 VHS tapes and DVDs amounting to hundreds of hours of video of men engaging in bestiality.

One of the videotapes featured Kenneth Pinyan shortly before he died on July 2.

Prosecutors later determined that the horse had not been injured.

"It was only after Pinyan died, when law enforcement looked for one way to punish his associates, that the legality of bestiality in Washington State became an issue [...] The prosecutor's office wanted to charge Tait with animal abuse, but the police found no evidence of abused animals on the many videotapes they collected from his home. As there was no law against humanely fucking a horse, the prosecutors could only charge Tait with trespassing."

According to Charles Mudede, co-writer of the 2007 documentary film Zoo, the men trained the horses to penetrate them by stripping, applying a horse breeding pheromone, and bending over.

In 2015, Mudede wrote that the men had a sexual fixation on large penises "that may have had nothing to do with horses".

He also believed Pinyan did not truly love horses and was not a true zoophile, although Pinyan had a cast created of the penis of his favorite horse, Strut.

The incident that killed Pinyan occurred at a 40 acre farm located in an unincorporated area in King County, Washington, 5 mi northwest of the city of Enumclaw.

Sgt. John Urquhart of the Sheriff's Office said that "typically", men were having sex with a horse whose name was not publicly disclosed on the property of James Michael Tait, a truck driver who lived in a trailer next to the farm, "but on this particular night it is my understanding that horse wasn't particularly receptive".
