CHAMBERLAIN, S.D. — Agnes Clement held an 8-by-10 photograph of her daughter, Crystal Schulz, as she addressed her daughter’s murderer. “This is my daughter Crystal,” Clement, of Dickinson, said Wednesday at the Brule County Courthouse. “You took one of the two loves of my life away from me. She’s my daughter Crystal.” Kent Davidson, 37, pleaded guilty to first-degree murder for the death of 26-year-old Schulz, who died in March 2013.
