Michelle Parker Disappearance: Family Releases Final Voicemail

"I'm here to tell you for a fact that she would never not come home to her 11-year-old son," Launer told ABC News. "She would never have taken off, done that to her brother, sister or mother. ... That's why we're crying every day. Every time it gets dark, that's another day that's gone by without her."

When Parker's brother Dustin texted Parker to ask where she was, he got an immediate response. It was one word: "Waterford." This message triggered a red flag for Launer.

"She would never have texted back 'Waterford.' Her texts are a book. In every text that she would send, she would have xo's, smiley faces, hearts," Launer said. "I personally do not think that was from her, not at all for one second, because she wouldn't have said that."

Parker's black Humvee was found the next day near the Mall at Millenia, about eight miles from the Waterford Lakes area.

Launer described her friend as a dedicated mother and hard-worker who juggled three jobs to support her children, bartending, working a tanning business and as a hair dresser.

Police at this point have no hard leads or suspects in the investigation.
