A pregnant 17-year-old St. Petersburg girl vanished more than a week go and hasn't been seen since.

Morgan Martin's family said she got a phone call just after midnight July 25th, went outside in a sweat suit and slippers, and went missing. Her mother, Leah Martin, said she and her family are very worried about the teen who is 4 months pregnant.

According to her mother, it was out of her daughter's character to have taken off and not told anyone. Knowing the circumstances of her disappearance, she was very blunt about what she thinks may have happened to her daughter: "I don't really think she's alive anymore," she said.

St. Petersburg Police have talked to Martin's friends, family and the father of her unborn baby, but they have not developed many leads to date. The family has put up fliers, as they try to spread the word, holding out faint hope Martin is still alive.

The missing teen is described as 5'2'', 175 pounds, with black hair and blue eyes. She was last seen wearing a white tank top, pink jacket with fur around the hood, gray sweat pants and the pink slippers. She went missing from her home in the 2800 block of 17th Ave. S.

She took her cell phone when she walked out of the house, but no calls have been answered since. She did not take her purse nor any money. No sign of foul play has been found and the girl's disappearance is still considered a missing persons case.
