EVERETT — An Arlington man whose blood-alcohol level was almost four times the legal limit shortly after a fatal collision told police he saw their patrol car lights and heard sirens but felt they weren’t directed at him, according to court papers filed Friday.

Randy Sedy, 45, was charged in

Snohomish County Superior Court with vehicular homicide, being involved in a hit-and-run accident and third-degree assault in connection with a series of collisions that injured a Marysville man and killed Meghan Stivers, a Lake Stevens woman, July 29. Arraignment is set for 1 p.m. Monday.

“It’s the most egregious driving I’ve seen in a vehicular homicide (case),” deputy prosecutor Tobin Darrow said.

A witness first spotted Sedy’s southbound pickup truck weaving across lanes and the center line and onto a sidewalk on State Avenue in Marysville, court papers said.

Marysville police attempted to stop a 1996 Dodge Ram around 11:15 p.m. after receiving reports of a possible drunken driver. The pickup later was seen driving westbound into the eastbound lanes of Fourth Street.

The driver didn’t stop for officers and crashed into two other vehicles before the fatal collision near the intersection of 33rd Avenue and Marine Drive just west of I-5, according to court papers.

A Marysville man was injured in one of the collisions. He was driving his BMW eastbound on Fourth Street. He stopped behind a line of traffic in the center lane just west of the intersection with Cedar Avenue.

He told prosecutors he saw Sedy’s pickup coming at him, first hitting the front passenger side of his car. The jolt caused his head to strike the driver’s door window. The pickup then backed up a few feet and accelerated forward, striking his car again. The pickup repeated the maneuver until it forced the rear of the BMW backward far enough to clear a path, according to court papers.

The Marysville man told prosecutors he has endured persistent pain in his jaw and was diagnosed with a knee injury and numbness to his face. He said he had nightmares afterward.

A Marysville police officer said he ducked behind his patrol car for safety when the pickup drove straight at him. It swerved away just in time. The officer said the driver “looked through me like I didn’t exist,” according to court papers.

Stivers had pulled her car off the roadway and was stopped in a gravel lot. She was working her way through college and had just finished a shift at the Best Western Hotel on the Tulalip Indian Reservation.

Sedy’s pickup crossed the eastbound lanes of Marine View Drive, drove over the eastbound curb and blasted through some bushes, according to court papers. It hit the driver’s side of Stivers’ Mercury Sable, pushing it backward 58 feet. She died at the scene from head injuries.

Sedy allegedly told police he drank a fifth of vodka and some beer at his home and was driving around looking for his daughter. His blood-alcohol level reportedly tested at 0.31; the legal limit in Washington is .08.

Sedy has a 2005 drunken driving conviction. In that case, court records show Sedy had a blood-alcohol reading of 0.27 after crashing into the back of a car on Broadway in north Everett. No one was injured.

Sedy remains in the Snohomish County Jail on $500,000 bail.
