Sarah Knysz, whose husband is accused of killing Michigan State Police Officer Paul Butterfield last month, will testify against her husband, according to her mother. Angel Burnham from Bay City says her daughter was dragged into a bad situation, and should not be facing charges.

When asked if Sarah was being charged in order to pressure her into testifying against her husband Eric Knysz, she told WOOD-TV her daughter didn't need to be persuaded. "There's no squeezing required. Absolutely not."

Knysz is seven months pregnant, and faces three charges in the September 9th shooting death of Officer Paul Butterfield.
