The Oklahoma State Bureau of Investigation is taking over the Henryetta mass murder investigation. Cameron Spradling, the attorney representing the Webster family whose relative was one of the victims, says OSBI is working to gather more evidence. Holly Guess, her children, Tiffany Guess, Michael Mayo and Rylee Allen, and their friends, Brittany Brewer and Ivy Webster were shot to death a week ago. The suspect Jesse McFadden committed suicide. He was a convicted sex offender. The OSBI brought in a U-Haul to get all the evidence local law enforcement left behind. Among that evidence were cellphones, computers, and items used in sex and bondage. The Webster family says they were told ponds on the property will be drained in the search for more evidence.
