While the deceased duo has been identified as the driver and helper of the vehicles involved in the crash, their names are yet to be known.
The mishap took place in the wee hours today while all three transport vehicles including a trailer truck were en-route to Sambalpur from Angul to deliver consignments.
It is suspected that, the truck which was moving ahead applied breaks due to some reason causing the other two trucks dash against each other in a rear-end series crash.
While the victim duo died at the spot remaining inside the badly mangled vehicles, Jarpada Police rushed their bodies for autopsy after recovery.
Further investigation is underway in the case.
