Green River, Utah, Mayor Ren Hatt Dies After Collision with Semi-Truck

Green River, Utah, is reeling after its mayor, Ren Hatt, was killed in a late-night collision with a semi-truck, a tragedy that has left the small community grieving the loss of a leader known for his steady presence and deep devotion to the city he served.

Green River, Utah, is mourning the sudden loss of its mayor, Ren Hatt, who was killed in a collision involving a semi-truck late Friday, December 5, 2025. City officials announced his passing the following day, confirming that the beloved local leader died at the scene of the crash on U.S. Route 6.

According to a statement from the Utah Highway Patrol (UHP) obtained by people, the fatal crash occurred around 9:40 p.m. local time. Investigators said a 2021 Freightliner semi-truck was traveling westbound when, "for an unknown reason," it veered across the centerline into oncoming traffic.

The truck struck the front passenger side of a 2020 Hyundai Palisade heading east — a vehicle later identified as being driven by Mayor Hatt.

After the impact, authorities said the Freightliner swerved back into the westbound lanes, while Hatt's Hyundai was pushed to the right and came to rest on the shoulder of the eastbound side. The 57-year-old mayor did not survive. The truck driver was not injured.

News of Hatt's death spread quickly through the tight-knit community of roughly 900 residents, many of whom viewed him as the steady, compassionate heart of the city.

On Saturday, Green River officials shared a tribute on the city's official Facebook page, expressing profound sadness over the loss of a leader who dedicated himself fully to the town he called home.

"Mayor Hatt loved this community deeply, and he served it with honesty, kindness, and unwavering commitment. We are grieving alongside his family, friends, and all who knew him," the post read.

Despite the shock, city officials reassured residents that municipal operations remain fully functional. In another public update, the city explained that preparations for the annual Light the Night celebration — typically a festive parade of illuminated floats along Main Street — would continue, but with a meaningful change.

This year's event will also serve as a candlelight vigil honoring Hatt's memory. The shift reflects a community-wide desire to come together in solidarity as they grieve.

Acting Mayor Bo Harrison, who stepped in following Hatt's passing, echoed that sentiment in a heartfelt message.

"Ren has given so much to the City of Green River," Harrison said. "Light the Night will give the community a chance to remember him and support his family at this difficult time."

The vigil is expected to draw a large turnout, as residents young and old prepare to gather with candles, share memories, and honor a man whose leadership left a lasting imprint on the city.

While investigators continue working to determine why the semi-truck drifted into oncoming traffic, Green River residents are focusing on healing — leaning on one another, reflecting on Hatt's legacy of empathy and service, and finding comfort in the traditions he cherished.

As the lights of the annual parade glow across Main Street, the event will double as a tribute to a mayor remembered not just for his role in city hall, but for the warmth and dedication he poured into every corner of the community he loved.
