Grandma, her husband accused of murder as Arizona investigators detail shocking child abuse case

Newly-released court documents are providing more information surrounding the death of an 11-year-old boy at an Old Town Scottsdale hotel.

The incident, according to officials, happened at an Extended Stay America hotel near Scottsdale Road and Goldwater Boulevard.

"When we showed up, the victim, who ended up being a juvenile, was taken to a local hospital, where they were later pronounced deceased," said Sgt. Kevin Quon with the Scottsdale Police Department.

"When they talk about a juvenile being murdered in my backyard, that's horrific," said Peggy Hicklim, who lives in the area.

It’s just really tragic, it’s just really hard," said Jordan Barclay who also lives in the area. "You just make friendships as you stay here, you know, so that’s why I think it hurts the most."

Suspects identified

Scottsdale Police say 51-year-old Stephanie Marie Davis and her husband, 33-year-old Thomas James Desharnais, have been arrested and were booked into jail on suspicion of first-degree homicide and two counts of child abuse.

Scottsdale Police say 51-year-old Stephanie Marie Davis and her husband, 33-year-old Thomas James Desharnais, have been arrested and were booked into jail on suspicion of first-degree homicide and two counts of child abuse.

In a statement, Scottsdale Police officials say they arrested two people, 51-year-old Stephanie Marie Davis and her husband, 33-year-old Thomas James Desharnais.

"Detectives discovered another young male child under the care of the defendants. The Department of Child Services responded and took custody of the young male child," officials said.

Davis is the grandmother of both the victim and the young male child, and the other young male child is noted to be the victim's half-brother.

"The individuals in this family are well known to SPD officers, who have contacted them on multiple occasions as the family members were panhandling in the vicinity of the Extended Stay America Hotel where they have reportedly resided since 2019," read a portion of the court documents.

Investigators noted that when David arrived at the jail for processing, multiple SIM cards were found concealed on her person, and in her belongings.

"The contents of which are unknown at this time," read a portion of the documents.

Court documents provide timeline of case

In court documents, investigators provided more information surrounding the juvenile's death, as well as a timeline of the case.

Davis, investigators say, called 911 from her hotel room at around 4:42 p.m. on Jan. 30, saying that the victim was found unresponsive and not breathing in the hotel room's bathtub.

"[Davis] also repeatedly stated that the male child had been ‘hurting himself’ all day," read a portion of the documents.

When police arrived at the scene, they found Davis performing CPR on the victim. Eventually, firefighters performed CPR on the victim.

"[Scottsdale Fire Department] personnel advised [Scottsdale Police Department] officers that they had removed ‘a half liter of water’ from [the victim] via oral suction during their life saving efforts," a portion of the court documents read. Investigators also noted that crews on scene noticed a number of injuries to both the victim and his half-brother.

The victim, according to investigators, was taken to HonorHealth Osborn Trauma Center Hospital, where he was later pronounced dead.

Davis, Desharnais provided different accounts on what happened

Davis, according to court documents, told officers at the scene that the victim struck himself in the forehead with a ‘wrench,' and also ‘cut himself’ in his private area.

"[Davis] further explained that earlier in the afternoon, the family was watching a movie on TV. [The victim] had reportedly struck himself on the head with the wrench, which [Davis] grabbed from [the victim] and she then ‘hid’ the wrench so that the child could not get it once again," read a portion of the court documents. "Sometime later, [the victim] had gone into the bathroom. [Davis] heard exclamations of, ‘ow, ow, ow’ coming from the bathroom. She went into the bathroom and found [the victim] with a laceration injury of [his private area]."

It was noted that neither Davis nor Desharnais sought any manner of medical attention for the victim.

Davis, according to court documents, told detectives that later on, the victim told her that he wanted to take a bath. Davis ran a bath for him, left him there, and then returned to the main part of the hotel room, where she got herself a puzzle book and took her medicine. 

Afterward, court documents say Davis returned to the bathroom and reportedly found the victim lying on his side, with his face above the waterline of the water-filled tub. She claims she then drained the tub, removed the victim from the tub, placed him on the ground, and performed CPR.

According to detectives, accounts by Davis differ on how long she was gone from the bathroom. She first told an SPD officer that she left the bathroom for 15 minutes, but later told the same officer that she left the bathroom for only 60 seconds.

Desharnais, however, provided a different account of what happened to detectives.

According to investigators, Desharnais said that as he entered the hotel room on Jan. 29, he heard Davis in the bathroom, striking the victim in the head with the metal ratchet.

"[Desharnais] estimated that [Davis] struck [the victim] at least three times in the head with the metal ratchet," read a portion of the documents. "The assault lasted approximately 10 seconds, and [the victim] was in the bathtub, naked when the assault took place."

After Davis left the bathroom, Desharnais said he gave the victim some paper towels to hold onto his bleeding head wound to try and slow the bleeding.

Desharnais, according to detectives, also noticed that Davis had used a knife to cut a portion of skin off the victim's private areas. Desharnais said he believed Davis did so because the victim has a problem with wetting the bed or peeing on himself, and that Davis is tired of cleaning the mess.

According to court documents, Desharnais was playing video games at around 4:00 p.m. on Jan. 30 when he heard what he initially thought was whimpering coming from an animal. He later learned that it was the victim who made the noise. 

Victim's grandmother abused him, investigators allege

According to court documents, Davis was awarded full custody of the victim in 2015, and the whereabouts of the victim's biological parents are currently unknown.

The victim's biological mother, according to investigators, is considered a suspect in a murder, while the victim's half-brother's biological father is in an out-of-state prison for child molestation.

Investigators noted that there are no records of the victim and his half-brother having attended any Scottsdale Unified School District schools in recent years. Davis, according to investigators, claims she home-schools the two children during a previous investigation into allegations of disorderly conduct. No charges were filed for that matter.

Investigators say over the past two to three months, Davis became more physically and verbally abusive towards both the victim and his half-brother.

"It's believed by [Desharnais] that [Davis] dislike the children because their mother ultimately is involved in the death of [Davis'] son," court documents read. "[Desharnais] believes that [Davis] physically abuses the children as a way to retaliate against the children's mother, who was part of her son's death."

In addition, investigators allege that Davis would starve the victim, and provide him with little to no food for several days and that Desharnais will sometimes sneak him food, just so the victim will get something to eat.

"[Desharnais] has indicated that [the victim] will go multiple days without any food, and is very undernourished and underweight," read a portion of the court documents.

Detectives also allege that Davis has struck both boys in the head with a wooden broom handle at least once, and would routinely grab and pull the boys' hair as they try to run away from her.

Desharnais witnessed other acts of abuse, detectives say

In an interview with detectives, Desharnais said he has witnessed Davis striking the victim at least four different times in the head with a metal ratchet, causing numerous lacerations of varying depth. 

Desharnais also told detectives that Davis would use needle-nose pliers to pinch and bend the children's fingers backward and that this has taken place on at least two different occasions to each of the boys, causing various cuts and bruising to the fingers.

Court documents say a search warrant executed at the hotel room on Jan. 31 turned up various evidence that was consistent with statements made by Desharnais during his interview, including blood evidence, a socket wrench hidden under a mattress, a broomstick outside the bathroom, and needle-nose pliers above a refrigerator

Investigators say they also found two mattresses and two box springs with what appeared to be dried blood, pillows with what appeared to be blood staining, a trash bag with what appeared to be human hair, and an animal shock collar, even though there are no pets.

DCS officials detail previous investigations

Officials with the Arizona Department of Child Safety say Davis and Desharnais were investigated three times in 2017. All the investigations were closed because the accusations were found to be unsubstantiated.

DCS officials released the prior reports involving the couple:

  • March 22, 2017: The child allegedly had a bruise behind his ear and scratches to his face, and the report alleged Davis hit him. Officials did not find evidence of abuse and they closed the case on April 14, 2017.
  • May 15, 2017: The boy reportedly had deep bruising under his right eye, and officials "did not find evidence to support the allegations." Community resources, which were not specified, were provided to the family, and the case was closed on July 17, 2017.
  • August 13, 2017: Desharnais was accused of picking the boy up and throwing him on the ground, causing discoloration to the boy's forehead. During the investigation, the family moved out of the state, and the allegations were reported to the proper out-of-state authorities. Again, the allegations were considered to be unfounded, and the case was closed on Sept. 18, 2017.

According to others, however, the reports of abuse did not stop there.

Courtney Lage said she reached out to authorities on two separate occasions.

"They did not behave like children should behave," said Lage. "They weren’t playing ball running around. You’re always very controlled in the room. It was sad."

Suspects appeared in court, cash-only bond set

Both Davis and Desharnais appeared in court on Feb. 1.

"These offenses are horrific, and can only be described as torture, your honor," said a county attorney to the presiding judge.

According to police, Davis and Desharnais are accused of first-degree murder and two counts of child abuse. Prosecutors had argued for no bond for Davis or Desharnais because of the severity of the crime, and the fact that neither are employed nor have a primary residence.

"The nature and circumstances to the offense are frankly horrific, involving allegations of the torture of multiple children on multiple occasions for a long period of time," prosecutors said. "The defendant poses a danger to the community.

Davis also spoke in court.

"Evidence that’s in your response, and it is circumstantial evidence. These kids were always taken care of," said Davis.

Ultimately, a judge set a cash-only bond of $3.5 million for Davis and a $1.5 million cash-only bond for Desharnais. Should either make bail, they will be placed under electronic monitoring, and neither will be allowed to have any contact with minors.

As the shocking incidents of abuse came to light, people living in the area sounded off.

"Everyone here is hurt that these kids were right under our noses being abused like that," said Barclay.

Celebration of life held

A memorial was held Feb. 6 near where the boy was found. A group of strangers, as well as city officials and first responders, wanted to honor the boy's life, even though they never knew him.

Courtney Lage lives across the street from the hotel and she saw signs of the reported abuse.

"I just want to emphasize they always had hats on and glasses and even in the summer, long sleeves obviously covering what police are saying now are bruises and scars," Lage said. "Just doing everything I can to get them some help, and it just wasn't enough, so anything we can do to try and prevent this moving forward. I'm just trying to give this little boy a voice, and his brother …"

Bikers Against Child Abuse also showed support at the event.
