Colorado State Senator Faith Winter, a Democrat representing the 25th Senate District, died Wednesday evening in a five-vehicle crash on Interstate 25 near Dry Creek Road in Arapahoe County, south of Denver. The 45-year-old lawmaker was the sole fatality in the collision that occurred around 6:20 p.m. on November 26, 2025, leaving three others injured.
The Arapahoe County Sheriff’s Office confirmed the crash details and stated that the cause remains under investigation. The deputy noted that determining the cause would take some time. The interstate remained closed until just before midnight as authorities worked the scene in Centennial, located in the southern Denver metro area.
Colorado Governor Jared Polis announced Winter’s passing in a statement late Wednesday, expressing shock at the loss. He described Winter as a fierce advocate for hardworking Coloradans, women, families and climate issues, noting he had known her for nearly two decades—first as an organizer for environmental causes, then as she expanded women’s representation in leadership, and finally as a state senator.
Winter’s family released a statement confirming her death and requesting privacy during this difficult time. “Faith led with empathy and love before all else,” the family said.
The senator leaves behind two children and was engaged to former state Representative Matt Gray, a fellow Democrat. At the time of her death, Winter was entering her 12th and final year as a state lawmaker due to term limits. She previously served in the Colorado House of Representatives before her election to the Senate, and earlier served on the Westminster City Council.
Winter held significant leadership positions in the Colorado legislature, serving as chair of the Senate Transportation and Energy Committee and as assistant Senate majority leader—the third-highest-ranking position in the chamber. Her district included Broomfield, Westminster and Northglenn, communities she represented with dedication throughout her political career.
Senate President James Coleman and Senate Majority Leader Robert Rodriguez, both Denver Democrats, issued a joint statement expressing their devastation at Winter’s passing. The caucus leaders emphasized that Winter served the state with compassion and an unwavering belief in the power of public service to improve lives, whether fighting for legislation to support mothers and families, championing groundbreaking transit policy, or supporting constituents in moments of need.
Winter’s legislative work touched multiple areas of public policy, with particular focus on housing protections, environmental issues and public transit. She held a bachelor’s degree in environmental management and biology, credentials that informed her approach to climate and transportation policy throughout her tenure. Her advocacy work extended beyond legislation, as she was known for encouraging people to come forward with experiences of workplace harassment.
The senator was a familiar presence at the Colorado State Capitol, often accompanied by her dog, Queso. Her daughter sold Girl Scout cookies outside the House and Senate chambers, and colleagues remembered Winter as someone quick to offer support to those having a difficult day. Her approach to public service combined warmth with skilled and tough policymaking.
Governor Polis ordered flags to be lowered to half-staff in honor of Winter’s passing. The flags will also be lowered from sunrise to sunset on the day of her memorial service, which has not yet been announced.
According to state procedures, reports indicate a Democratic vacancy committee in Senate District 25 will determine who will fill Winter’s seat for the remainder of her term through 2026. The selection process will take place after officials and the community have had time to grieve the loss. Colorado Democratic Party chair Shad Murib noted that Winter was always there to challenge people to do unimaginable things in the service of those who need the most help.
Photos from the scene showed significant damage to several vehicles, including a truck on its side. The conditions of the three injured individuals have not been publicly disclosed as authorities continue their investigation into what caused the collision.
Winter’s death represents a significant loss for Colorado politics, cutting short the career of a lawmaker who had built a reputation for dedication to public service and advocacy for working families. Her colleagues at the state capitol remembered her not only for her legislative accomplishments but for the thoughtfulness, innovation and humility she brought to every aspect of her work representing the people of Colorado’s 25th Senate District.
