Authorities have been searching for Michelle Parker since she disappeared on Nov. 17. That was the day an episode of the reality show ran in which Parker and her former fiance argued over her lost engagement ring.
The Orlando Sentinel reports Parker's mother said investigators called her in Wednesday to identify a cell phone. She says it was Parker's but officers didn't say when or where they found it.
Police say Parker's ex-fiancDee Dale Smith is their primary suspect. Smith's attorney has said his client has done nothing wrong. Smith and Parker have twin children.
