An Aurora man will spend up to six months in jail for engaging in sex acts with his dog, and the dog will be euthanized because it has become aggressive after being removed from the abusive home.

An Arapahoe County judge on Tuesday sentenced Frederick Manzanares, 51, to six months in jail and two years of supervised probation for participating in sex acts with the dog and his former girlfriend. Manzanares pleaded guilty to two counts of misdemeanor animal cruelty in September.

And, Bubba, the male Akita mix who also goes by Biscuit, was to be euthanized Tuesday afternoon, said Michael Bryant, a spokesman for the city of Aurora.

Bubba had been living at the Aurora Animal Shelter since authorities took custody of him this summer. The dog has become progressively aggressive at the shelter, Arapahoe County Deputy District Attorney Amy Ferrin said at the hearing.

“Bubba is not doing well at all,” Ferrin said.

Judge Cheryl Rowles-Stokes considered the fate of Bubba in her sentencing decision, she said.

“This dog cannot safely be adopted,” Rowles-Stokes said at the hearing before reading her sentence. “This dog cannot safely be transferred.”

“This dog cannot recover,” she said.

Manzanares, dressed in a dark suit, spoke in the courtroom before Rowles-Stokes read the sentence. He said that he now recognized that the sex acts were wrong and that he didn’t mean to harm the dog.

“I know those desires are morally wrong and they will never manifest themselves again,” he said.

Manzanares also asked if he could be allowed to work with Bubba to help rehabilitate the dog for any potential adopter. His voice cracked as he spoke about Bubba.

Instead, Rowles-Stokes forbid Manzanares from owning, caring for or cohabiting with any animals during his probation. He will also complete treatment for his deviant sexual behavior as part of his sentence.

In a letter to the Arapahoe County District Attorney’s Office, the animal shelter manager said the city also had charged Manzanares in municipal court for allowing a dog to run at-large and for keeping an aggressive dog.

When Manzanares surrendered Bubba to animal control in July he told officers that he had concerns about the officers’ safety in handling the dog. The manager, Jenee Shipman, gave Manzanares permission to go to the shelter to help officers vaccinate and place a collar and identification tag on Bubba.

“The dog has exhibited unpredictable behavior, and shows signs of aggression towards veterinary services staff, volunteers, community service workers and staff members that the dog is not especially familiar with (staff who clean, fee, provide enrichment and treats daily,” Shipman’s letter said.

Shipman went on to say, “It is my opinion this dog is not a safe adoption candidate or transfer candidate based on the history, kennel behavior and continued increase in aggression observed daily.”

Manzanares’ former girlfriend and co-defendant, Janette Solano, pleaded guilty to one count of animal cruelty and received a 24-month deferred judgement and sentence, meaning she will not be convicted or serve jail time unless she violates the courts’ restrictions during the two-year period.

Ferrin, the prosecutor, requested that Manzanares be sentenced to 18 months in jail — the maximum penalty — for the first count of animal abuse and five years supervised probation for the second. Manzanares’ attorney, Christopher Decker, asked the judge to consider a deferred sentence like the one Solano received. Decker said it would be an act of gender bias if Manzanares received a harsher penalty than Solano and alleged the two were equal participants in the crimes.

Solano called police in March 2017 to report a domestic violence incident. When Aurora police officers arrived, she told them that she and Manzanares had been arguing and that she was leaving him because he had been pressuring her to have sex with the dog.

Solano told police that Manzanares had sent her videos and literature about bestiality for six months.

Police later found a custom bench that Manzanares designed to facilitate sex acts with the dog inside a mobile home near the couple’s home, according to the man’s arrest affidavit. Manzanares filmed the sex acts with the dog and used a hormone spray to excite the animal, the affidavit states. Police found photos and videos showing Solano having sex with the dog while Manzanares was nearby.

Colorado outlawed sex with animals in 2007 as part of an update to animal cruelty laws. Bestiality was previously legal in the state.
