Michael A. Cavagna, 38, appeared Friday from Walla Walla County Jail via the internet.
Walla Walla County Prosecuting Attorney Jim Nagle accused Cavagna of first-degree unlawful possession of a firearm, vehicular assault, attempting to elude a pursuing police vehicle and use of drug paraphernalia.
According to court documents, a Washington State Patrol trooper spotted Cavagna speeding through Dixie and pulled him over.
WSP initially reported the chase started in Dayton but according to court records it started in Dixie.
When the trooper saw a gun on the dashboard of Cavagnaâs car and asked him about it, Cavagna fled and led police on a chase that exceeded 120 mph down U.S. Highway 12 and into Walla Walla.
