Jurors Friday night convicted a 19-year-old woman accused in the 2014 death of a Piedmont teen and chose life in prison as punishment.

Chloe Marie Thomas, of Oklahoma City, was found guilty of second-degree murder. She showed no reaction when Oklahoma County District Judge Cindy Truong announced the verdict.

During closing arguments Friday, Thomas never looked up from her Bible, even when prosecutors called her a “cold-blooded killer.”

“It's so hard thinking someone so young could be so cold hearted but that's what the evidence shows,” Oklahoma County Assistant District Attorney Jimmy Harmon told the jurors before they began deliberating Friday afternoon.
