Patricia Ann Murphy, 29, now faces up to five years in prison when she is sentenced Feb. 18 on that and two other charges.
Murphy told Judge Karen Miedema that she had consumed marijuana and a methamphetamine prior to operating her vehicle on Randall Street in Coopersville on Aug. 11, 2018. Murphy crashed into another vehicle, causing serious injury to the occupant.
Murphy also had her young daughter in the car and was driving on a suspended license at the time of the crash.
Ottawa County Prosecuting Attorney Ron Frantz said the crash victim suffered three spinal fractures and was airlifted from the scene for treatment at Spectrum Health Butterworth Hospital in Grand Rapids.
Murphy pleaded guilty to one count driving under the influence causing serious injury, one count driving on a suspended license causing serious injury and one count operating a motor vehicle in the presence of a controlled substance with a child under age 16 in the vehicle.
In exchange for the pleas, prosecutors will dismiss at sentencing one count operating under the influence causing serious injury, one count driving on a suspended license causing serious injury and one count open container.
