GUIXI, Jiangxi Province, Dec. 25 (Xinhua) -- More details were released on Tuesday regarding an auto accident in east China that killed 11 kindergarten students and devastated the families of the "left-behind" children involved.

The driver of the minivan, which belonged to a school and was overloaded with 15 children and two adults at the time of the accident, was speeding on a rural road undergoing repairs and plunged into a three-meter deep pond on its way to a kindergarten early Monday. Only four children and the two adults survived, police in the city of Guixi, Jiangxi Province, said.

The latest probe results show that the children, aged 4 to 6, were students of the privately-run Chunlei Kindergarten in Binjiang Township. The school's principal, 35-year-old Zhou Chun'e, was driving the van on Monday.

Police said Zhou overloaded the van, which had a designed seating capacity of seven, and "drove improperly," resulting in the accident.
