HOUSTON -- The search is on for a group of men who shot three women during two attempted robberies at taco stands Saturday night in southeast Houston.Houston police said a mother and her daughter were working at the taco truck on Winkler near Juliabora when two men demanded money, but before they could hand it over, the robbers shot at them. The mother, 37, tried to shield her daughter, but the bullet hit her daughter.The mother was transported to Memorial Hermann and the 17-year-old daughter taken to Ben Taub with non-life threatening injuries. Police have been able to talk with them to get a description of the suspects.After leaving the first taco truck, the two male suspects ran away from the scene toward another truck about three blocks away.Dash cam video of the second robbery shows what police believe to be the same men. They shot the only woman running that stand at least five times. She was taken to an area hospital in serious condition. Police have not released any other details."The money that they got has no comparison to value of these ladies' lives that have definitely been affected by their behavior," Ken Nealy with the Houston Police Department said. "Again, that's why we're seeking the public's assistance in identifying these suspects."Authorities said they are looking to see if the robberies are connected.The suspects are described as two black males.If you have any information in these robberies, contact Houston police.
