LOCHBUIE, Colo. - Trenton Parker is looking for individuals willing to help gun down 24 horses on his property.

The Weld County Sheriff's Office says Parker, 64, is distributing fliers seeking executioners because he is upset that he faces a 90-day jail sentence for contempt of court for failing to clean up his property.

Parker was first ordered to remove converted mobile homes, which violate county zoning codes, from his property on Dec. 31, 2007.

On the flier, Parker says he's looking for riflemen to publicly execute 24 registered horses as a way to protest the zoning codes. He says the shootings will happen at high noon on Sept. 5.

"I've never seen anything like this before in my experience in law enforcement," Shane Scofield with the Weld County Sheriff's Office said.

The sheriff's office stresses that anyone who participates in the shooting would face felony animal cruelty charges.

"I would like to think that after reading something like this, there would not be a person in the county, or a person around in the state, that would actually be interested in taking somebody up on this," said Scofield.

Deputies say Parker is due in court on Sept. 8 on the contempt of court charges.

Investigators also say that Parker left a threatening voicemail at the county zoning department, giving a graphic description how he would kill his horses.

According to an incident report, Parker said, "It would be done in public, he would kill one every day for a week on the front steps of the court house, at CSU and other public places. He would stab them in the belly three or four times, killing the foal and then he would bash the mare's brains in."

Parker also said he would starve the horses because he didn't have any sheds to put hay in "because the courts were making him get rid of all buildings and trailers."

Parker was arrested for an unrelated assault in March, but the victim decided not to pursue the charges.

The National Horse Rescue Association has learned of the flier and says it's making an effort to "stop the slaughter."
