Oregon State Police (OSP) troopers are asking for the public’s help locating the driver of a semi-truck they believe may have been rear ended on I-5 shortly before 1:00 A.M., near milepost 253, in the Salem area. Preliminary information indicates that a silver Lexus passenger car was traveling southbound on I-5 near milepost 253 which was an active construction zone during this time. The driver of the Lexus, name withheld pending next of kin notification, died at the scene. Troopers believe the Lexus may have rear-ended a semi-truck which may not have known it was struck and not stopped. They are asking anyone with information on this incident or who may have seen the crash to contact the lead investigator, Trooper Eli Breen, at the Northern Command Center at 503-375-3555.
