what happened to Kanei's family when the rebels came

Kanei is a Mende boy who escaped the rebels' attack on his village with his parents, but lost his two sisters and three brothers in the chaos. He and his parents escape in a boat, but the boat capsized when rebels threw the passengers into panic by shooting at them. Kanei swam to the other side of the river and witnessed many people drowning in the river whiel the rebels laughed at their suffering. He follows the other survivors in the hope of locating his parents, whom others tell him have passed through the area. Kanei is among the six boys Beah encounters after his month of isolation in the forest.
