A months‑long investigation by the Thurston County Sheriff’s Office (TCSO) into an October 2025 hit‑and‑run in Yelm concluded this week with the arrest of a suspect, according to a public announcement posted by TCSO on its official Facebook page. The collision seriously injured a pedestrian and killed his dog, prompting sustained community attention and a lengthy search for the driver.

The crash occurred on Yelm Highway S.E. when Andy, who was walking with his dog, Kevin, was struck while using a crosswalk. According to reporting by MyNorthwest, the family stated on their fundraising page that the crosswalk’s flashing signal was active and that Andy was wearing a light‑up walking vest at the time. Multiple vehicles were reportedly stopped when a gray sedan entered the crosswalk at speed, briefly paused after striking the pair, and then fled.

In the hours that followed, an unidentified passerby transported the injured dog to an emergency veterinary clinic. According to the family’s description on their GoFundMe campaign, Kevin died from internal injuries. Andy suffered several injuries, including a broken foot and broken ribs, and was treated at a hospital.

According to TCSO’s statement, investigators received assistance from the Puyallup Police Department the night of the collision after a Flock Safety camera notification flagged the suspect vehicle. Law enforcement located the unoccupied car days later and seized it as evidence. Over the following months, deputies executed multiple search warrants as they worked to identify a suspect. TCSO stated that probable cause was established last week. Deputies then contacted the suspect’s family to coordinate a surrender, and the suspect was later booked into jail.

While the case stems from Thurston County, its circumstances echo traffic‑safety concerns seen across the wider Southwest Washington corridor, including Cowlitz County, where local agencies have documented increases in pedestrian‑involved collisions on major arterials. The Yelm investigation highlights the role of automated license‑plate cameras and interagency cooperation in identifying fleeing drivers — tools increasingly used by law enforcement throughout the region.

According to the family’s fundraiser, donations are being used to cover cremation costs for Kevin, as well as Andy’s medical expenses including emergency care, imaging, and surgery. Remaining funds are planned for donation to the Tacoma Humane Society.

Why this matters

Pedestrian safety continues to be a major concern along high‑speed connectors throughout Thurston, Lewis, and Cowlitz counties. While this case occurred outside Cowlitz, the investigative steps and community response offer insight into how similar incidents are handled regionally, and how technology and public reporting can support long‑term investigations.

Community‑level traffic enforcement and pedestrian‑safety measures remain ongoing topics of discussion in cities like Longview and Kelso, where residents have repeatedly raised concerns about crosswalk visibility, driver behavior, and nighttime conditions. The Yelm case illustrates the potential consequences when a driver fails to stop and the extensive process required to identify a suspect months later.

No additional information about court proceedings or charging decisions had been publicly released by TCSO at the time of publication.
