Tierra, 25, was last seen wearing white capri pants and a black and white top. She is described as 5'6", weighing about 200 pounds. She has black hair and brown eyes.
Each and every volunteer is desperate to find the mother and her unborn child. It has been more than a week since family members have seen or spoken to Tierra.
"It's like sometimes I just get numb," said Tierra's mother, Rose Adams. "We've called hospitals, she's not there. They've checked the jail system and she's not in there. So, where could she be?"
It was Monday of last week when the father of the Tierra's unborn child says that the two got into an argument. He told authorities that he was on his way to drop her off at her mother's house, instead he says put her out of the car around 1am and left her on the side of the road.
"An area where she was last seen has been thoroughly searched by our people and we can't find her right here so we are expanding," said Frank Black, a field coordinator with Texas Equusearch. "There are some reasons for me to believe that she's deeply in danger, if not in harm already."
Fear for the life of Tierra and her unborn baby daughter grows, but so does the anger towards Tierra's boyfriend, who was the last person to see her.
"You just take it upon yourself to let her out at 1 o'clock in the morning and you already see this is (not a livable area). It's not like there are homes out here -- look at all of this wooded area. It's not a good thing," said Tierra's mother.
Tierra is scheduled to give birth on Valentine's Day and plans to name her little girl Sidney.
Police are not calling Tierra's boyfriend a suspect in this case.
Anyone wanting to volunteer to search can do so by calling 713-301-6813.
