Three family members died and one was injured during a boat crash on the Mekong River in Kandal province on Saturday night, according to Kim Vanna, Kien Svay district’s deputy police chief in charge of the penal bureau.

The deceased included a father, mother and their 4-year-old daughter.

The family’s 6-year-old son survived the crash.

“After two days, relatives began to wonder why the family was missing,” Kim Vanna said.

“A neighbour found the boy on the river bank on Monday and noticed many pieces of a wooden boat floating on the water.”

The boy told the police that another boat had crashed into his family’s boat while they were fishing, Kim Vanna said.

He added that police are searching for the second boat and its crew.
