A 13-year-old boy was driving the pickup truck that collided head-on with a minibus on Tuesday, killing six students of a New Mexico university, their head coach, and both occupants of the pickup truck, authorities said.
During a Thursday news conference, the vice-chairman of the National Transportation Safety Board (NTSB), Bruce Landsberg, said a preliminary investigation revealed that the pickup truck had a spare wheel in place of its left front tire, which was blown out before impact, causing the truck to swerve in front of the minibus.
