Fort Collins Flagger Charged: Who Is Liable for the Crash?

Four months after a fatal crash on a Fort Collins construction project, police have announced a charge. On Monday, July 6, 2026, around 6:20 p.m., a semi-truck working on the project struck a bicyclist at East Mulberry Street and Whedbee Street. Catherine Withrow of Fort Collins died at the scene. The driver stayed. (City of Fort Collins, July 2026)

On Wednesday, November 4, 2026, Fort Collins Police Services said a 64-year-old construction flagger, Rudolph Baldivia, was booked on one count of criminally negligent homicide, a class 5 felony. Police say the semi driver followed established safety protocols. They say the flagger put himself and Withrow in an unsafe place, where the driver could not see either of them.

An answer after months of waiting does not ease a family’s loss. It does change the legal picture.

What the Charge Does and Does Not Mean

Under C.R.S. Section 18-3-105, criminally negligent homicide covers a death caused by criminal negligence. Police stress that a charge is only an accusation, and Baldivia is presumed innocent until proven guilty.

The criminal case asks whether a crime occurred. A civil case asks who must answer for the harm, and it uses a lower standard of proof. The two run on separate tracks. A civil claim does not depend on the outcome of the criminal case.

Why the Police Finding Shifts the Focus

Investigators say the driver was within safety protocols. That points attention away from the truck and toward how the work zone was run. The question is no longer only who stood where. It is who trained the flagger, who supervised him, and who planned the traffic control.

Who May Share Responsibility

Several parties could be examined in a civil investigation:

•     The flagger, whose positioning police have described as unsafe.

•     His employer, which can be responsible for an employee’s negligence on the job.

•     The contractor in charge of the traffic control plan, flagger training, and site supervision.

•     Any other company or agency that owned, designed, or oversaw the project.

Police found the driver within protocols, but a civil case can still test that finding. Records and testimony may add detail that a criminal review did not need.

Work Zones Run on Rules

Work zones follow traffic control standards, including the Manual on Uniform Traffic Control Devices. Those standards address flagger training, placement, and visibility. A civil investigation would compare what the plan required with what happened on July 6.

How Fault Is Divided

Colorado uses modified comparative negligence under C.R.S. Section 13-21-111. Fault is divided among everyone whose conduct contributed. Police say the flagger placed Withrow in the unsafe spot, and that bears directly on how any share of fault is assigned to her.

A Deadline That Applies If a Public Agency Is Involved

If a government entity owned or oversaw the project, claims against it follow stricter rules under C.R.S. Section 24-10-106. Written notice is required within 182 days under C.R.S. Section 24-10-109. Counted from July 6, that window closes in early January 2027. Nothing reported says a public agency bears responsibility. We raise it because a missed notice deadline cannot be undone.

Wrongful Death Claims in Colorado

Under C.R.S. Section 13-21-202, surviving family members can bring a wrongful death claim when another person’s negligence causes a death. C.R.S. Section 13-21-203 covers losses such as funeral costs, lost financial support, grief, and loss of companionship.

The general deadline is two years from the date of death under C.R.S. Section 13-80-102. An employer or contractor may carry commercial liability insurance, which is often the main source of recovery in a work zone crash.

Evidence That Needs Protecting

Records held by companies can be lost or discarded over time. Useful items include:

•     The traffic control plan and any changes made that day

•     Flagger training and certification records

•     Daily site logs and communications between the flagger and the driver

•     Camera footage from the site and nearby businesses

•     Event data from the semi-truck

•     Witness statements from construction personnel and bystanders
