William Allery has signed a plea agreement in connection with a sex trafficking ring in Great Falls.

During a change of plea hearing on Sept. 18, he entered an Alford plea, which is a defendant acknowledging there’s enough evidence to convict but not admitting to the facts. It carries the same significance in sentencing as a guilty plea.

Allery was arrested in February 2024 and charged with felony counts of sexual intercourse without consent; promoting prostitution; endangering the welfare of a child; criminal endangerment; and tampering with a witness or informants.

A charge of accountability for criminal distribution of dangerous drugs was filed later as a separate case against Allery and combined with the initial charges for the plea agreement.

James Amato was arrested at the same time and charged with felony counts of sexual assault; promoting prostitution; endangering the welfare of a child; criminal endangerment, criminal possession of dangerous drugs and accountability for criminal distribution of dangerous drugs.

Amato was sentenced in April after entering an Alford plea in February.

Allery has been held in the Cascade County Adult Detention Center since his arrest.

In the plea agreement, Allery entered an Alford plea to felony counts of endangering the welfare of a child, tampering with witnesses or informants and accountability for criminal distribution of dangerous drugs.

The county attorney’s office recommended five year prison sentences for each count, suspended and consecutive to each other and is moving to dismiss the felony charges of sexual intercourse without consent, promoting prostitution and criminal endangerment.

District Court Judge Elizabeth Best set his sentencing for Nov. 4, but since that’s election day, it will likely be rescheduled.

Allery is set to be released from jail with a GPS monitor once he signs a waiver of extradition.

During the Sept. 18 hearing, Allery said he understood that a jury would likely convict him on those counts and it was in his best interest to accept the agreement.

Michele Levine is prosecuting the case for the Cascade County Attorney’s Office and said that the victim’s grandparents might want to submit a letter for sentencing as they did in Amato’s case.

She and County Attorney Josh Racki spoke to the victim on Sept. 17 about the plea agreement and she reiterated that her deposition last fall, with Allery and Amato present, was traumatic and that coming to court to testify would not be helpful for her mental health or treatment progress.

“It’s hard for her to be in the same room,” with Allery and Amato, Levine said, and it “takes a toll on a crime victim, especially a young teen victim like herself.”

Levine said that without the victim’s cooperation, trial would be unpredictable and that juries are not always kind to victims of sexual abuse, so the plea agreement provided some certainty and accountability for Allery through probation.

Releasing him on GPS before sentencing is a chance to see how he behaves in the community and the county attorney’s office is not bound by their sentencing recommendation if he violates those conditions, Levine said.

“This is your chance not to blow it,” Best told Allery.

The victim’s grandmother contacted The Electric about the October 2024 deposition. To protect the identity of the victim, we are not naming the grandmother either.

The deposition was held to get the victim’s testimony in case she ran away before the trial that had been previously scheduled.

The victim’s grandmother attended and told The Electric that the victim was questioned for roughly six hours with Allery and Amato sitting just a few feet away, staring at her from across the table.

Allery didn’t have an attorney present, but Molly Woodman, Amato’s attorney, “asked questions including why she was on probation, where she got her clothing, and who she sold drugs for. [The victim] was made to feel like a criminal.  She finally shut down and could not finish. She was sobbing, shaking, and begging to be taken back to the JDC,” the victim’s grandmother told The Electric. “Court trials for rape victims are as traumatic as the assault. Victims are forced to relive the attacks. They have to talk about it in front of numerous people and on camera. [The victim] is a child. She is terrified. She is being held in the JDC. She has numerous mental health issues which are not being addressed. I believe she is currently a victim of the justice system in Great Falls, and this [deposition] was exceedingly harmful.”

According to the charging documents, a Great Falls Police detective conducted a forensic interview with a then 15-year-old girl on Feb. 14, 2024 who told detectives about a man named “Bill,” later identified as Allery.

The girl said she met Allery through another boy when she was on the run and doing drugs. The boy told her Allery could help her “get into the game and make money.”

She told detectives that Allery advised her she could sell sex, according to court documents.

The victim told detectives that she went to meet Allery and the other boy also took her to “Tony’s” house where he had a hot tub in his garage, near Super 1 Foods. Tony was later identified as Amato, according to court documents.

The victim told detectives that Allery lived behind Poppy’s on 15th Street South and he would have her have sex with other men to get money and drugs, according to court documents.

She told detectives that other girls were at Amato’s residences to have sex with men, “like it was their job,” according to court documents.

The victim told detectives that Allery raped her multiple times and that she didn’t know all of the other men who also raped her, according to court documents.

She said that Allery threatened to hurt her mother if she told anyone about what was happening, according to court documents.

The victim told detectives that Allery gave her drugs for having sex with him and that he injected what he said was meth into her arm, according to court documents.

At Amato’s, she told detectives that she was raped in the hot tub in the garage by multiple men and she was afraid they would hurt her.

A GFPD detective drove the victim to the 2500 block of 11th Avenue South where she had left her backpack in a dark SUV. She told detectives that she had underwear in the bag that were dirty and would have forensic evidence on them, according to court documents.

GFPD officers later spotted the SUV and saw drug paraphernalia in the vehicle, which was impounded.

Detectives also drove the victim to an apartment building in the 1000 block of 5th Avenue North where she said she had left other belongings, including a phone she had used to communicate with Allery.

Detectives drove the victim to Amato’s house in the 3200 block of 9th Avenue South and officers contacted area neighbors who said there had been “odd comings and goings” from the house in the alley, specifically the garage, that the garage light was frequently on in the middle of the night, that multiple vehicles show up in the middle of the night in the alley and sit for awhile, and that people go into the garage for a short time, then leave, according to court documents.

“They all said they noticed ‘sketchy’ people show up to the garage in the alley at all hours of the night,” according to court documents.

During the 2015 investigation, during which Amato was a woman’s source of meth, Amato told investigators that he cut down the meth because he felt bad for females he was selling it to, that he gave money back to one woman because he felt bad for her, that he allowed some of the girls to stay in his garage overnight while his wife was sleeping in the house, according to court documents.

In a subsequent interview with the victim, she told detectives that Allery and Amato kept the money from other men who had sex with her. She said Allery and Amato believed her to be 16, but found out she was 15 and still raped her, according to court documents.

The victim told detectives that Amato tried to have sex with her, but she declined, but he had her touch him and that he had videos of himself having sex with other girls.
