Most were taken to local hospitals with "possible, but non-life-threatening injuries," Harris County Sheriff Ed Gonzalez tweeted Sunday afternoon.The 42-year-old driver "failed to control speed while negotiating the curve causing the bus to roll on its right side," Gonzalez tweeted,Fourteen of the passengers were transported to area hospitals with "possible, but non-life-threatening injuries," Gonzalez said.The driver was not injured and did not appear to be intoxicated, Gonzalez said.It was not initially clear exactly how many people were on board, Gonzalez said, because the bus was making various stops to drop people off and pick others up.A woman who said that her grandchildren were involved in the crash told CBS Houston affiliate KHOU that the bus was carrying "kids and babies.""
