Six people, two of them civil guards, were killed when a truck ran over them on a highway in Seville. The driver, 59, has spent his first night in prison, accused of six crimes of reckless homicide and three of serious injuries due to recklessness.

The main hypothesis that investigators are working with is that the driver fell asleep at the wheel. “Statistically, 90% of accidents are due to the human factor,” says the deputy prosecutor for Road Safety, Luis Carlos Rodríguez León.
