In 2008, Illinois emergency response came upon a garage fire and a man was found crushed beneath a truck. Upon first glance, the victim was the homeowner Ari Squire. Investigators turned to forensic science to determine if they were dealing with a tragic accident or a carefully orchestrated murder. With the discovery that Ari had recently hired a Home Depot employee named Justin Newman, who had recently disappeared, the case focused on the search for Squire.
