Rush had been drinking prior to crash
Two adult "acquaintances" riding in the vehicle with Rush did not require immediate hospital treatment after they fled on foot from the accident site, Smith said.
The individuals confirmed to investigating deputies that Rush had been drinking alcohol before the accident, police said. Smith said they were not charged.
Authorities later determined Rush was wanted on forgery charges by authorities in Winchester, Va.
Smith said Steerman was about to stop the vehicle for suspected DUI when it turned onto a private drive.
The vehicle then turned around, but by the time Steerman changed direction on Apple Harvest Drive toward Martinsburg to catch up with Rush, the vehicle was out of his sight, Smith said.
Collision causes power outage
"He saw a flash," Smith said of the apparent transformer explosion that happened after the vehicle struck the utility pole. The collision caused a power outage in the area for about 3 1/2 hours, including the intersection of W.Va. 45 and Interstate 81, police said.
Smith estimated the distance between where the deputy turned around and the wreck site was about a mile.
Sgt. William Henderson gave first aid to Rush at the accident scene and is the investigating officer for the wreck, which remains under investigation, police said.
