School bus driver, 24, is arrested after five elementary students are killed and 23 are injured in Tennessee crash that saw the vehicle leave the road at speed and wrap around a tree. A bus driver who was transporting 35 students from an elementary school has been arrested after at least five children were killed following a horrific crash. Johnthony Walker, 24, has been charged with multiple counts of vehicular homicide, reckless endangerment and reckless driving, Chattanooga Police Chief Fred Fletcher told CNN late Monday night. The bus that Walker was driving crashed and wrapped around a tree Monday afternoon, authorities confirmed. Five children died at the scene. Walker is charged with five counts of vehicular homicide, but could face more charges as the case proceeds to a Hamilton County Grand Jury, Fletcher said. It is unclear at this time what led to the crash. Fletcher said that speed is being investigated 'very, very strongly' as a possible factor, adding that driving conditions were clear and dry. He said 'a warrant has been issued to remove the informational box on the school bus and review the video', CNN reported. District Attorney Neal Pinkston initially told WRCB that six people had died. However, police reconfirmed that the actual fatality count was five victims and not six. Twenty-three more victims were sent to Erlanger Hospital after the bus crashed. Fletcher said 35 schoolchildren were on the bus Monday afternoon. Bloodied students lay on stretchers, while other children walked away dazed with their parents after the Monday afternoon crash. At the scene, parents were heard crying and screaming 'that's my baby' as they arrived, CNN reported. Fletcher did not have information about the extent of injuries. He said the crash was 'every public safety professional's worst nightmare'.
