According to a probable cause affidavit filed in August 2010, Luis Ruiz was accused of taking a pickup for sale on a test drive and not returning it. He was arrested a week later when the pickup owner's father spotted the vehicle and called police. Luis Ruiz fled on foot and was arrested with a woman in the 2700 block of SW 31. The woman with Luis Ruiz was carrying a sack containing 12 small baggies that tested positive for cocaine in a field test, according to the affidavit.
Luis Ruiz was not charged in connection with the incident.
Texas court records show that Luis Ruiz was also charged in 2008 with unauthorized use of a vehicle in Brazos County.
Police have previously said they were considering several suspects who had been jailed on charges of drug and human trafficking.
A confidential witness told police she was kidnapped and forced to watch as members of a human trafficking ring tortured and murdered Saunders to send a message to others to cooperate with their illegal activities.
In December 2011, Francisco Gomez, 32, and Jimmy Lee Massey, 33, were named as persons of interest in connection with Saunders' death. Both men remain in the Oklahoma County jail, but neither has been charged with murder.
According to court records, Massey admitted to kidnapping a woman and making her watch as Saunders was tortured and killed Oct. 9. Massey also described how Saunders' body was dismembered and left in a field behind the Homeland grocery store at NW 23 and Rockwell Avenue.
