Two men died after the van they were in plunged down a precipice along the North Coast Road, Maracas, on Wednesday.
Police said the van was carrying concrete blocks to a worksite when it collided with a truck and a car.
The incident occurred at about 2 pm.
The passengers of the van have been identified as 52-year-old Terry De Gazon, and Derek Gonzales of Cunupia.
Members of both families, who were at the Forensic Science Centre on Thursday, were too distraught to speak to Guardian Media.
