In that county, investigators have identified about 16 close family members and associates, including Christopher Lee Stout, believed to be involved in the same criminal enterprise, Booth said. Members of the group tend to use aliases and move frequently, he said.

In Oklahoma County, he had been charged with grand larceny and concealing stolen property. Christopher Lee Stout had also been charged in Cleveland County with grand larceny and making false declaration of ownership to pawnshops. In Grady County, he had also been charged with grand larceny and assault and battery, court records show.
