Mississippi prosecutors have dismissed indictments against a man in the shooting death of a former state lawmaker and the earlier burning of a building, saying they need more time to investigate. The murder and arson charges against Billy Lamar Brooks were dismissed without prejudice, which means a grand jury could consider new charges later, according to a document filed Friday in Yalobusha County Circuit Court. Republican former state Rep. Ashley Henley, 40, was shot to death in June 2021 outside the burned-out mobile home in a rural area where her sister-in-law, Kristina Michelle Jones, was found dead in December 2020.
