HARRIS COUNTY - There are new clues in the disappearance of a Spring teenager who has been missing since April 2010.
Ali Lowitzer's mother told Local 2 Wednesday that the family's private investigator has received several tips that her daughter was taken to Ohio.
Those tips included people on the street recognizing Ali's photo.
They also led to a raid at a prostitution house. Officials said there was no sign of Ali, but one of the girls taken into custody claimed she knew her.
Police in Ohio are continuing the investigation and will interview the women and men caught in the raid.
Ali's mother said this is the strongest lead they have gotten since her daughter, who was 16 at the time, was seen getting off the school bus nearly four years ago.
