Stevens said Tweed had met Perez at a party, but they were not close friends. Tweed declined to speak with the media.
Officials said Perez may have left the state Oct. 11. He was last seen that day near Interstate 35 and Robinson Street in Norman. He may have been trying to hitchhike, possibly to California, police said.
Cole said he does not think Bethany residents should be alarmed but should always be vigilant and report suspicious activities.
Tweed's name came up in the investigation after Perez's mother filed a missing-person report with Oklahoma City police. In the report, she said Perez had been threatened by a man over a girlfriend.
Rachel Laraway, 38, claimed her son was having problems with a white male named “Tweet” or “Tween.”
Laraway told police she had not seen her son since Oct. 10 and Perez said he had been helping the girlfriend of the man named “Tweet” or “Tween.” The man went to Perez's apartment and said he “was gonna take it to the next level,” according to Laraway's report to police.
Perez had gotten his girlfriend and another girl pregnant, his mother states in the report.
Perez had not gone to work or school for a week and had a paycheck waiting for him at the Olive Garden on Memorial Road, Laraway stated in the report filed Monday.
On his Facebook page, Perez calls himself a Juggalo, which is how fans of the musical group Insane Clown Posse refer to themselves. The band's lyrics are controversial as they touch on themes such as cannibalism, murder and necrophilia. Many of Perez's Facebook friends are fans of the band, and photos on Saunders' Facebook page show her wearing an Insane Clown Posse T-shirt.
Perez is shown on a Facebook page photo holding a hatchet.
He has a lengthy criminal history out of Tulsa County including assault and battery on a Department of Juvenile Affairs employee, possession of a stolen credit card and larceny from a house.
Laraway has not confirmed whether Perez knew Saunders.
A relative of Saunders, who asked not to be identified, said Wednesday she did not know any family members who had heard of Perez before Tuesday night.
An autopsy on Saunders' body has not been completed, state medical examiner spokeswoman Amy Elliott said. Elliott said toxicology reports — that could take several weeks to complete will be needed — before a cause of death can be determined.
