Cole identified the person of interest as Francisco Gomez, 31. Gomez is also wanted on numerous drug charges.
Massey, who was arrested Nov. 4 on drug complaints, told police he was the one who forced the witness into the car and made her watch Saunders' torture and killing, the affidavit states. Massey identified Saunders from a photo.
Police said Massey gave them graphic details about Saunders' torture and the dismemberment of her body that only someone present would have known. He also identified others in the room during her killing.
Court officials said Massey is being held without bond.
“There are several more people involved in this homicide,” Cole said. “We want everyone to answer for their involvement no matter how small their role was.”
Saunders' friend, Melissa Wagner, 19, said Massey's arrest gives her some piece of mind for her friend. She said she didn't know Massey or Gomez or their connection with Saunders.
Wagner said other friends have had similar reactions to the arrest, adding that it's nice to know the case is being solved.
“I was afraid it would be one of those things we would never know what happened,” she said. “We're all just grateful that the Bethany police department has solved it.
