She had bumps and bruises but was otherwise unharmed when she was spotted Monday morning walking under an Interstate 610 overpass in west Houston by a passer-by who had seen media reports that she was missing.
Courtney Roland was found close to The Galleria shopping center in western Houston, as indicated by nearby police.
Authorities say additional information will be released later Monday.
