The Lone Tree Police Department is investigating the deaths of a man and his son as a murder-suicide, as details about the father's allegedly abusive relationship with the mother and son come to light.

The two were found dead in a Lone Tree apartment about 2:30 a.m. Sept. 21, according to city officials. A previous day's hearing likely would have resulted in giving the mother full custody of the child, the mother's lawyer said.

Anthony Tesoriero, 48, and his son, Ty, 10, were found dead at the Contour 39 Apartments at 9045 Yosemite St. by police officers. The officers were conducting a welfare check, according to a statement provided by the city. A police spokesperson said no notification to city residents or the media was given after their deaths were discovered because there was no threat to the public.

The police spokesperson said no further information will be released as to the cause and manner of death until the investigation is complete and the final autopsy reports are made available.

Ty's mother, Jing Tesoriero, held a memorial for Ty on Oct. 5 at Logos Central Chapel in Centennial.

Ty's pastor, art teacher at Acres Green, his martial arts instructor, his babysitter and a family friend painted Ty as an energetic, friendly kid with a big heart.

"I never thought we would be saying goodbye to Ty like this. He was so full of life and all of the promise of things to come," Jing Tesoriero said during the ceremony. "His future was an open book waiting to be read. A story... I looked forward to being a part of."

Caroline Cooley, Jing Tesoriero's attorney, provided Colorado Community Media a certificate of findings from the Sept. 20 hearing. Cooley said the court was prepared to give Jing full custody of Ty following a series of violations outlined in the hearing.

Of the alleged violations, Anthony Tesoriero changed Ty's school without authorization from the mother or parenting coordinator and cut ties with a drop-in daycare for custody exchanges. The document outlines several instances of exchanges where Ty was resistant to go with his mother for various reasons, all of which, the document suggests, were caused by manipulation from the father.

Jing Tesoriero said she missed 242 days of parenting time with Ty since May 25, 2018.

Jing and Anthony Tesoriero divorced in Florida in 2015. Jing Tesoriero started a new relationship with her current husband. Anthony Tesoriero remarried as well.

"Ever since that day (of the divorce)," the hearing document states, "Father has resorted to virtually every possible tactic involving threats, intimidation, slander, and harassment to destroy Mother's life...ruin Ty's relationship with Mother, and harass virually every professional who has touched this case."

The background of the case alleges Anthony Tesoriero tried to get his ex-wife fired from her job, created fake dating profiles under her name so she would be harassed, made false "confessions" on her Facebook page pretending to be her and stalked and harassed her on occasions "too numerous to list individually here."

Jing Tesoriero, her new husband and Ty moved to Colorado later in 2015, the court document shows.

Anthony Tesoriero first contacted the Douglas County Department of Human Services on Oct. 30, 2015, making accusations later to be deemed unfounded by both Florida and Douglas County authorities.

The Douglas County Department of Human Services issued a dependency and neglect action because "the conflict between the parties was harming Ty's wellbeing." The same action recommended temporary custody be given to Jing Tesoriero and restricted the father to supervised therapeutic visits only.

Jing Tesoriero's new husband reported receving several threatening emails from Anthony Tesoriero. Jing Tesoriero also reported receiving text messages saying "kill yourself," "push me any further & many will suffer" and "1 day it will be the last day 4 us."

On July 14, 2016, Anthony Tesoriero pleaded guilty to violating a protection order against Jing Tesoriero.

The document provided a statement from a Douglas County Human Services caseworker: "There is concern that Mr. Tesoriero has unrealistic expectations of the child's behavior and struggles to put the child's needs before his own."

In September 2016, human services conducted a pyschological evaluation of Ty. The evaluator expressed a "multitude of concerns regarding Ty's health," the document reads.

On Dec. 8, 2017, human services recommend a 50-50 parenting split for the time being.

Douglas County Director of Communications Wendy Holmes released a statement on behalf of human services:

“This is a devastating loss for the family and the entire community is grieving. As you know, state law prohibits release of information about child welfare matters. In situations like this, in accordance with state law, the State Department of Human Services will conduct a child fatality review. At the conclusion of the review, the state will publicly release their findings.”   

A public records request for the Lone Tree Police Department's reports of the suspected murder-suicide was denied because the reports are incomplete at this time, according to a police spokesperson.

"Ty has touched so many people's lives in this community," Jing Tesoriero said during the memorial. "I want everyone to remember his silliness and his goofiness because this is what Ty was and this is what we all want him to be remembered as."
