Arraignment for Kimberlee Singler, the Colorado Springs woman accused of killing two of her children and attempting to kill a third, was postponed until November after the defense successfully argued that more time is needed for discovery and the completion of forensic testing.

Singler, 37, had been scheduled to face formal charges at a hearing Wednesday before 4th Judicial District Chief Judge William Bain.

After granting the continuance, which Bain said he originally had been inclined to deny in an effort to “keep the case moving expeditiously,” he told both sides to prepare for an early April 2027 trial.

“The court would note that the case itself is approaching its third anniversary,” Bain said.

The crimes of which Singler is accused most likely took place sometime on Dec. 18, 2023, but went undiscovered until the early morning hours of the following day, when Colorado Springs Police Department officers responded to a 911 burglary report at a condo in the Palomino Ranch Point community in eastern Colorado Springs.

Officers discovered two deceased children, according to previous Gazette reporting, and investigators later found evidence they allege indicated Singler, who at the time was in a custody battle with her ex-husband, was responsible for their deaths and the injuries to the surviving child.

In the days after the killings, Singler was reported missing and soon after was found to have fled the country for the United Kingdom. The FBI obtained an arrest warrant and, after an extradition hearing, Singler was escorted back to the U.S. from Britain and booked into the El Paso County jail on Dec. 23, 2023.

There she has remained, as the protracted legal process continues to play out.

This isn’t the first time Singler’s attorneys have requested a continuance due, at least in part, to what they describe as delayed or late receipt of documents and forensic test results from the prosecution, a fact Bain addressed at Wednesday’s hearing — while also stressing that an early spring trial date was non-negotiable.

“No exceptions … so again, I encourage the people to be frank and candid with the defense as to what you’re working on,” Bain said.

Prosecuting attorney Christina Perroni pushed back on implications that the delays were deliberate or orchestrated, saying the situation was due to a backlog resulting largely from sheer volume.

“There is a lot of discovery, and there is still ongoing forensic testing. We have multiple items that are still at CBI (the Colorado Bureau of Investigation),” Perroni said Wednesday. “So based on that, we would not be objecting to a continuance.”

Singler’s arraignment hearing is now scheduled for Nov. 18 at 11 a.m. 

Her trial is expected to begin the week of April 5.
