Washington law enforcement officials are actively searching for a sixth suspect believed to be at large following the Chelan Hills Fire, a catastrophic wildfire that resulted in the death of one person and the destruction of over 100 structures. Five individuals are currently in custody and facing serious charges, including first-degree manslaughter, first-degree arson, and malicious mischief. The incident occurred on July 4 near U.S. Highway 97 in Douglas County, where investigators allege that fireworks, specifically Roman candles, were fired from a moving truck, igniting dry grass and sparking the 10,000-acre blaze. The fire claimed the life of 69-year-old Robert Lister, injured six firefighters, and caused more than $6 million in property damage. During recent appearances in Douglas County Superior Court, defendants Julian Alexander Mikityuk, Valentin Tabunscic, and Michael Yakimov entered not-guilty pleas to the charges. A fourth defendant, a 19-year-old, was held on $1 million bail, while a fifth defendant's arraignment was delayed as he sought a change in appointed counsel. Douglas County Sheriff Tyler Caille confirmed that while five of the six individuals identified as being in the vehicle have been arrested, detectives are finalizing probable cause requirements to obtain an arrest warrant for the remaining suspect. Sheriff Caille emphasized that all individuals involved are considered complicit, regardless of their specific role in launching the fireworks, and stated that the investigation remains active with all necessary resources being utilized to locate the sixth person. The U.S. Marshals Service has assisted in previous arrests, and authorities have vowed to bring the final suspect into custody to ensure justice for the victim and the impacted community.
