According to Richland County Sheriff Leon Lott, none of the 18 children were injured after they and the bus driver -- also uninjured -- were held hostage in the morning by an individual later identified by Fort Jackson as 23-year-old Jovan Collazo from New Jersey. The incident lasted about an hour. It all started when Collazo, dressed in a physical training uniform and armed with an M4 rifle, jumped a fence and left the military post at around 7:00 a.m. ET (1100 GMT). Lott said the trainee initially tried to flag people down and get into cars, eventually ending up at a bus stop where the children were boarding a school bus that he also got on.
