This picture, provided by the Southeast Missourian, shows Jacque Sue Waller. The woman was last seen by her estranged husband, James "Clay" Waller, when she drove to his Jackson home June 1 to pick up her son.
Waller, a manager for the insurance company Blue Cross Blue Shield, was filing for a divorce from her husband who authorities say is a former police officer.
When Waller arrived at her husband's home to pick up her son, Maddox, the child was not there, police said. Clay Waller allegedly told investigators that he and Jacque had an argument before she "walked away mad," according to Jackson Police Chief James Humphreys.
James "Clay" Waller, a former police officer, has been named a "person of interest" in his wife's disappearance. The woman's sister said she believes Waller lured Jacque to his home on June 1 to kill her.
Police found Jacque's Honda Pilot abandoned along Interstate 55 in Missouri the morning after she was reported missing. Waller's purse, keys and cellphone were not found inside the vehicle, and police say there has been no activity on her credit cards and phone since her disappearance.
