A 61 year old La Pine man was killed in a traffic accident near Wickiup Junction last night. Sheriff's officials say Wesley Powell died when he pulled out in front of a semi on Highway 97. Sheriff's officials are investigating Thursday night's fatal crash to see if alcohol was a factor. Sergeant Vance Lawrence with the Deschutes County Sheriff's Office says it appears that drinking did play a role. “A combination of icy windshield; drinking may be a factor. Warn people that even a few drinks can impair your judgment and reflexes." Highway 97 was clocked in both directions three miles north of La Pine for about two hours. The driver of the Peterbilt was a 27 year old man from California and he wasn't cited. Lawrence says the semi wasn't able to stop in time to avoid the accident.
