A 26-year-old triathlete training on the roads of eastern Aurora was killed earlier this month when a white Subaru Outback struck him and drove away, leaving his body undiscovered for hours along South Powhaton Road. Police have identified the man as Arthur Williams and are asking the public to help identify the driver who fled, a search that has stretched on for more than a week with no arrest.
Williams was riding southbound on South Powhaton Road while training for a triathlon when he was struck, according to Ward 2 City Councilmember Amy Wiles, who shared details about the victim on social media. Wiles described Williams as an avid cyclist who regularly rode the roads of eastern Aurora to prepare for competition.
Cyclist's Body Found Hours After Overnight Crash
A passing driver discovered Williams' body around 9:30 a.m. on July 27 in the 1600 block of South Powhaton Road, according to KUSA-TV. That discovery led investigators to estimate the collision occurred sometime between 9:30 p.m. on July 26 and 6:30 a.m. the following morning. Debris recovered at the scene initially suggested the striking vehicle could have been either a 2005-2009 Subaru Legacy or a 2015-2019 Subaru Outback, the station reported, before detectives narrowed their search specifically to a white Outback.
Investigators Narrow Search To White Subaru Outback
In a public appeal, Aurora Police Dept said the crash happened just after midnight on July 27, within the broader overnight window investigators had already identified, and that the wanted Outback may be missing its passenger-side fog light and have a cracked driver's-side headlight. The vehicle may also show damage to its front passenger-side headlight and hood, police said. Tipsters are asked to reference case number 26-155696 when contacting investigators.
The white Outback was last seen on city traffic cameras heading southbound on Gun Club Road near East Quincy Avenue on July 27, per the same appeal. Aurora Police Department launched a centralized Real Time Information Center in 2025 that links municipal cameras, license plate readers, and traffic sensors, a system that, according to Colorado Politics, helped detectives locate the footage of the Outback along Gun Club Road.
Powhaton Road's Growing Traffic Danger
Wiles noted that South Powhaton Road is a heavily traveled arterial route for residents of several fast-growing eastern Aurora developments, including Adonea, Traditions, Harmony, Murphy Creek, Cross Creek, and Sky Ranch. The road connects those master-planned communities, making local residential camera footage and neighborhood tips central to the investigation, she said.
A Statewide Surge In Roadway Deaths
The crash fits into a broader trend of rising roadway fatalities across Colorado. Statewide, 701 people died in traffic crashes in 2025, up from 689 the year before, including 18 bicyclist deaths and 126 pedestrian fatalities, according to Colorado Department of Transportation data reported by The Denver Gazette.
Arapahoe County, which includes parts of Aurora, recorded 79 pedestrian fatalities between 2020 and 2025, placing it among the state's top five highest-risk counties for vulnerable road users, per a CDOT safety report cited by Kiowa County Press. Nationally, 15% of all police-reported crashes in 2023 involved a driver who fled the scene, resulting in 2,872 deaths, with more than 70% of those victims being bicyclists or pedestrians, according to an AAA Foundation for Traffic Safety study reported by The Auto Channel.
What Comes Next For The Driver, If Found
Once identified, the driver would face serious legal exposure. Under Colorado Revised Statutes § 42-4-1601, leaving the scene of a crash that results in death is a Class 3 felony carrying mandatory driver's license revocation and up to 12 years in state prison, according to Justia Law.
Community Vigil Set For Powhaton Road This Thursday
Family members and local supporters have scheduled a vigil and press conference for Thursday at 6 p.m. at South Powhaton Road and East Jewell Avenue, near the crash site, to honor Williams and appeal for tips, according to a Facebook announcement from organizers.
Anyone with information is asked to call Metro Denver Crimestoppers at 720-913-STOP (7867), where tipsters can remain anonymous and may be eligible for a reward of up to $2,000. Aurora police can also be reached at their non-emergency line, 303-627-3100, or at 911 in an emergency. Hoodline first reported on the fatal crash days after it happened, and this case remains one of several fatal hit-and-runs Aurora police have investigated in recent months.
