Tierra Adams

Tierra Adams, 25, has been missing for more than two weeks.

Adams was last seen Jan. 29 around 1 a.m. in northwest Houston. Her boyfriend told police she got out of his car after they had an argument.

More than 20 searchers with Texas EquuSearch had been looking for Adams from the ground and the air, but they haven't found any sign of her.

"Being out here in the dark, you know, anything could have happened," said Frank Black with Texas EquuSearch. "And no one has seen here. There've been no tips or leads as to her being seen any place, and that bothers us."

Searchers organized by Quannel X will meet at The Church at Willow at 1265 North Houston Rosslyn at 2 p.m.

That's near where Adams was last seen. The searchers will go door to door in the neighborhood to distribute flyers and talk with possible witnesses.

The boyfriend has not helped with the search, but police say he is not considered a suspect.
