(McMinnville, OR) -- A Yamhill County woman is expected to plead guilty to DUII in connection with her daughter's death. OregonLive reports that investigators believe the 27-year-old fell out of the car in August while her mom was behind the wheel. After she and her daughter went to a wedding, Jennifer Weathers called authorities with a story claiming the younger woman had gotten mad and left the vehicle. Weathers' lawyer says she'll admit to driving drunk at her next court appearance in February.
