KINGSTON, July 16 (Xinhua) -- An overloaded motor vehicle ran off the road and plunged into a river in Jamaica on Saturday, leaving at least six dead and another one missing.

Witnesses said the driver misjudged the turn to Flat Bridge before his vehicle plunged into the Rio Cobre river.

Preliminary investigation showed there were eight persons in the five-seat vehicle. But when the vehicle was recovered from the water, only five were found inside.

The five, along with another victim whose body was found later in the river, were sent to the hospital, where they were all pronounced dead. The police said it appears the victims drowned before help could reach them.

Currently, there is only one confirmed survivor, a 19-year-old young man. Investigators are still searching for the other passenger.
