In May, the same trailer was raided by police, who said they removed thousands in cash and a small cache of drugs. Investigators said they also found evidence that Wilson had recently sold large quantities of marijuana, reportedly about 100 pounds.
Wilson, when questioned about Patton's death, reportedly admitted that he used the double-wide trailer to sell drugs.
Girl still missing
Paz has been in the news recently after he was questioned in the disappearance of Jaray Wilson, 16, who was last seen Oct. 15.
Custer County Sheriff Bruce Peoples told The Oklahoman in October that Paz was questioned because “his name kept coming up” during interviews with Wilson's friends and acquaintances.
Peoples said there was speculation among those same sources that Jaray Wilson may have been a victim of human trafficking, but investigators were unable to link Paz to the girl's disappearance.
Paz has been arrested several times in Oklahoma since 2003, including two weapons charges.
Buckmaster and Southerland also have extensive criminal records, with each logging several drug arrests dating to 2005.
Southerland also was charged Monday with possession of drugs in Caddo County.
Patton, the shooting victim, had been arrested at least three times on drug charges since 2007.
