Hannibal Woman Sentenced in Robbery and Murder Case
A Hannibal woman is sentenced to 20 years in prison for her role in a 2013 robbery and fatal shooting at a Hannibal convenience store.
Krystal Tresler was sentenced Wednesday in Ralls County Circuit Court. Authorities say Tresler was among five people who planned to rob the store where Adrienne Arnett was shot and killed as she was working just west of Hannibal and that Tresler provided her van and gave the driver directions. Three co defendants previously pleaded guilty. Another co defendant goes to trial later this year. Tresler's attorneys say they plan to appeal.
