MINNEAPOLIS — A St. Paul woman says she was celebrating her pregnancy by mixing wine with a painkiller when she sped through downtown Minneapolis and struck and killed a college student.

Teisha Randle has pleaded guilty to criminal vehicular homicide in the October death of Austin Conley, a 20-year-old Augsburg College student. Some of Conley’s family members cried as they sat in the courtroom gallery Monday when Hennepin County District Judge Daniel Moreno accepted Randle’s plea.

A prosecutor told the judge he would ask for a four-year sentence. Sentencing is scheduled April 22.

Defense attorney Carolina Lamas said that Randle ended her pregnancy after she was criminally charged.
