Texas EquuSearch founder and director Tim Miller told ABC13 they couldn't disclose much about their efforts over the weekend, but crews looked in an area near a southwest Houston neighborhood in a wooded area.
Saturday's efforts came a week after a search in Missouri City.
Miller said Saturday they were led to the location off Fondren Road due to what he called credible information, but didn't give details on what that information might have been.
While Saturday's search didn't turn up anything significant, Miller said his team received new information that they are pursuing but didn't elaborate.
It is unclear what type or style of clothing Ashley was wearing when she disappeared.
