The trial starts today for a Platte County woman charged in the murder of her former son-in-law. Brenda Williams is the second of three people charged in the case to go to trial. Her husband, Jimmy, has been sentenced to life in prison. She’s accused of being part of the plan to kill ex son-in-law Thad Mize, who was chased down and killed by people in a van. The prosecutor says the murder was committed so the Williams’ daughter could try to collect on a fake life insurance policy. The daughter will be tried later.
