A 28-year-old woman who ran into oncoming traffic on Interstate 25 in Lone Tree early Feb. 17 committed suicide, according to the Douglas County coroner.
Tiffany Engstrom died of blunt-force trauma about 1 a.m. after a pickup truck traveling north on I-25 near Lincoln Avenue struck her. Authorities do not yet know where Engstrom lives. The coroner’s office said they believe she is a transient.
The pickup’s driver saw the woman running west into the northbound traffic lanes, and tried to avoid hitting her, according to police, but struck Engstrom with the front corner of the truck. Engstrom was pronounced dead at the scene.
The driver appeared sober and provided a blood sample voluntarily, but was arrested and jailed after officers learned the driver was operating a vehicle without a valid license.
