The Brief A sheriff's report says the Mississippi teen charged in the killings was suspected in multiple burglaries and auto thefts. Investigators said deputies came under gunfire before arresting the teen after a nearly two-hour standoff. Defense attorneys argue there is no direct forensic evidence linking the teen to the fatal shootings. The Mississippi teenager accused of killing an elderly couple in their home was already familiar to local law enforcement, with deputies identifying him as a suspect in many burglaries and vehicle thefts in the area, according to an incident report obtained by Fox News Digital.

During a preliminary hearing in July, family members testified that Hobbs had previously worked for the Blairs, performing tasks such as cleaning around their property before the alleged killings. An incident report from the Simpson County Sheriff's Department, obtained by Fox News Digital, described Hobbs as a troubled juvenile and said investigators believed he was connected to several other crimes in the community. ...When we first arrived I and other Deputies and Investigators believe the suspect could be a troubled juvenile known to us as Cordarius Hobbs who is also suspected of many other home burglaries as well as auto theft in this immediate area, the report states.
