Three people were crushed to death along the Isinya-Kajiado road on Wednesday night.
The three, a driver and two loaders, had alighted to mend a broken chain they were using to tow a truck that had mechanical issues from Kajiado town.
Isinya OCPD, Stephen Weda, said the accident happen when the three were trapped in between the two trucks after another truck carrying a full load of limestone hit the stalled lorry from behind.
The driver of the truck that hit the stalled on from behind was seriously wounded and he is now recuperating from Kajiado Level Four county hospital.
