Players and team employees have been eagerly anticipating the planned development, with General Manager George Paton even putting up a rendering of the new facility in his office in 2025 as a selling point to potential free agents who came through the building.

Dorotik had fentanyl and methamphetamine in his system, including three times the amount of fentanyl that can cause a fatal overdose, according to the sheriff’s office.

Arsenault and Julia Weishaar were arrested and charged in August 2024 with manslaughter and 10 felony drug charges in Dorotik’s death, including distribution of a controlled substance resulting in death and conspiracy to distribute, according to Arapahoe County court records.

Weishaar took a deal and pleaded guilty to conspiracy to distribute fentanyl resulting in death, a class one drug felony, in October 2025, court records show. The deal dismissed all other charges, including manslaughter, and she was sentenced to 10 years in the Colorado Department of Corrections.

Hundreds of law enforcement officers from across metro Denver responded to Adams City High, 7200 Quebec Parkway, around 1 p.m. after someone called 911 to report a bomb at the school and the presence of an active shooter, with wounded people supposedly inside the facility, authorities said.

Officials put the school on lockdown, with students and staff secured inside classrooms. Adams City High currently enrolls 1,422 students, according to state records.

Police entered the school, going room to room to clear the building and look for a shooter and any victims, officials said.

Once inside, officers found “what appeared to be a blood trail in several areas of the school,” Commerce City police said.

After searching the school for two hours, police determined there were no victims and no real threat. But they found and arrested two students “who were covered in what looked like fake blood — the same substance officers had encountered in parts of the building,” police said.

“For many, calls of this nature are their worst nightmare,” Commerce City police Chief Darrel Guadnola said in a statement. “Whether a first responder, a parent, a teacher or a student — most will never forget this day. The notion that this call may have been part of a prank is highly disturbing and pulled valuable law enforcement resources away from real emergencies in the Denver metro.”

No students were injured during the lockdown, but one experienced an unrelated medical issue and was transported to a hospital by paramedics as a precaution, . That student was later released to their parents.

District officials also noted that social media posts shared by people who weren’t employees of the district spread inaccurate information that may have alarmed families.

“Adams 14 encourages the public to avoid sharing unverified information on social media during incidents, as it can unintentionally increase fear and confusion for families, divert law enforcement resources and place additional strain on those working to protect students,” Adams 14 officials said in their statement.

Law enforcement officers from the Adams County Sheriff’s Office, Colorado State Patrol, Westminster Police Department, Thornton Police Department, RTD Police Department, Arvada Police Department, Aurora Police Department, the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives responded to the school.

Neither child has been publicly identified, though the 5-year-old boy was a kindergartener at Timberline Elementary, Principal Mary Bowens wrote in a Wednesday email to parents.

Authorities responded to the boy’s home, a rental property in the 5200 block of South Jericho Way, at about 5:30 p.m. Tuesday, . The street, filled with single-family homes with wide driveways and green yards, remained closed Wednesday afternoon as the investigation continued.

Authorities have not said how the killing unfolded or offered any details about the attack. Arapahoe County Sheriff’s spokesman Anders Nelson declined to offer any information on the nature of the 5-year-old’s injuries or say why investigators considered the death to be first-degree murder, citing the early stage of the “very complex investigation.”

The 5-year-old boy’s cause of death remained under investigation Wednesday, sheriff’s officials said.

“It is with great sadness that I want to share with you that one of our kindergarten students has died unexpectedly,” wrote in the email to parents. “There is currently an active police investigation and law enforcement asked the district not to release the student¶¶Ňőap name. We ask the community to honor the family’s privacy at this time.”

The sheriff’s office said Wednesday that there was no ongoing danger to the community and that everyone involved in the boy’s death has been identified.

Children as young as 10 can be criminally prosecuted in Colorado. Typically, hundreds of Colorado children between the ages of 10 and 12 face criminal charges each year.

State lawmakers have on multiple occasions introduced bills aimed at raising the minimum age for prosecution to 13, but those bills have failed. Both of the recent efforts — in 2022 and 2023 — included exceptions that would have allowed children as young as 10 to still be prosecuted for homicide. Children younger than 12 cannot be charged as adults and their cases must proceed in juvenile court.

Timberline Elementary plans to offer students and staff support through its mental health team and in the coming days, Bowens wrote.

“There is no right or wrong way to cope with loss, but there are some things that adults can do to help students work through this difficult time,” Bowens wrote. “I want to remind you how important it is to have conversations with your own child and remind them that if he or she is struggling with this loss to seek out the support of an adult.”

Bowens ended the email with a reminder to “Please hug your children — nothing is more important than our kids.”
