HOUSTON --The family of a missing teenager is renewing the call to help find her, more than a year after her disappearance. Ali Lowitzer, 16, was last seen getting off her school bus in north Harris County in April of last year. Her parents and the Laura Recovery Center are organizing a new search to find her this Saturday. They're asking for help from volunteers age 18 and older and anyone who can bring four-wheelers or horses. Volunteers will meet at North Woods Baptist Church in Spring at 7am Saturday.
