SPOKANE, Wash. -

The Washington State Patrol is investigating an Eastern Washington University student in connection with a traffic accident that killed two college students near Colfax.

Investigation records in the vehicular homicide probe say 21-year-old Erica Polito Moss was drinking in a Pullman bar in the early morning hours of Feb. 21.

The Spokesman-Review reports that after a couple hours of sleep, Moss attempted to drive back to Cheney with three other young women all of them students at EWU.

The documents say her blood alcohol content registered a 0.081, which is above the legal threshold to drive.

Shortly before 5 a.m., her small car slid on what investigators say may have been black ice on state Highway 195. The car collided with a semi-truck pulling two trailers.
