COLUMBUS, Ohio - A family is desperate to find a missing pregnant woman. 22-year-old Samantha Greenlee was last heard from October 8. Two days later, her apartment burned down. The family is planning a prayer vigil October 21. "Every day you just lose a little bit of that hope. You wonder now, 'where is she?' 'Who did something with her?' Because she's not just missing on her own," said Greenlee's grandmother, Darlene Byas. It's been 12 days since anyone's heard from Greenlee. Her family has no idea what happened. "She would have called her sister, her mom or her dad," said cousin Stacee Sheridan. That's what tipped everyone off, days without communication."The only reason we knew was when my daughter went there to check on her and her car was there," said Byas. The family found Greenlee came home from work at the Lennox Bravo restaurant the night of the eighth, didn't return for any shifts after and never used her phone again. She was three months pregnant, but missed a doctor's appointment on October 10. That same day, the apartment she shared with her boyfriend went up in flames. He says the dog kicked over a candle.
