The family were travelling north from the Algarve towards Mourao in the district of Evora near the Spanish border.The tragedy happened around 1.40am Saturday morning on the IP2 main road in Castro Verde around halfway to their final destination.
The hire car they were travelling in caught fire after the crash and local reports said they had all burned to death, although it will be up to forensic experts to decide whether some or all of the occupants were already dead when flames took hold of the vehicle.
The Portuguese man travelling in the other car, 26-year-old Ruben Goncalves, has also been pictured locally.
Local reports said Ruben worked at a zinc-copper mine southeast of Castro Verde called the Neves-Corvo mine. He had a son aged around four.
Pictures from the crash scene showed the wrangled wreckage of one of the two vehicles involved in the accident on the wrong side of a crash in a field where a blaze took hold after the collision and had to be put out by firefighters.
The crash happened on a bend on the IP2 where signs shows the speed limit is 80kmh.
