Like every parent in Valencia that day, Victor Matías had quickly changed his plans, fearing what could be on the way.

The rain was still thundering down, but by now – early evening – he had managed to leave work early, safely pick up his boys from nursery and was about to make their favourite dinner – croquetas.

The crispy fried rolls of mashed potatoes, stuffed full of cheese and ham, would be a treat for Izan, 5, and Rubén, 3, while their mum Marta finished her late shift at the supermarket in town.

We have pieced together the tragic chronology of what happened next.

Our picture emerges from the testimony of neighbours and relatives we spoke to, as well as what Victor was able to recall himself along with other first-hand accounts given to local media.

The crushing story of the Matías family has generated huge attention in Spain. Many have followed updates on “Los niños desaparecidosas” – the missing children – as they have been frequently described.

But this one family’s grief is many people’s grief as it’s a nightmare replicated across the Valencia region which was hammered by flash flooding nearly two weeks ago, killing at least 219 people.

More than 90 are still missing.

When we arrived at the family home, a few days after the deluge, it was languishing in a sea of destruction.

That startling statistic – a year’s worth of rain had been dumped on some parts of Valencia in a matter of hours – became easy to believe as you took all this in.

Huge metal containers – broken free from their articulated lorries – rested at unfathomable angles amid a jumble of cars, crumpled furniture and treacherous mud.

One of the few things still intact was the door to what had been the boys’ bedroom; the bright, white individual letters spelling their names standing out in a sea of brown.

Picking his way through this mess was Jonathan Perez, their next-door neighbour, who began to relive the terrifying sequence of events. “It was madness” he said. “I’ve never seen such force.”

Jonathan explained to us how the raging torrent had scooped up trucks parked next door to the Matías family home with one smashing through an external wall.

He said that Victor had explained to him how he’d grabbed his sons in his arms as the water dragged them all outside.

Then – despite his desperate efforts to keep hold of them – they were gone.

Victor was found around four hours later, more than 200 metres away.

He had been clinging to a tree.

His mother – the boys’ grandma – revealed that Victor had been ready to throw himself into the torrent and surrender to his fate, but then stopped.

He told himself he could not leave his wife alone.

For 5 year old Izan and 3 year old Rubén, few places felt safer than the playground that was their house and garden.

Their aunt, Barbara Sastre, told us they were like little bugs – “bichetes” – an endearing description to convey how they buzzed around, that is, when they weren’t absorbed by their cartoons.

“They were such happy kids” she told us.

Izan and Rubén’s parents had bought the property from a man called Francisco Javier Arona.

Javi – as he’s known – told EFE, the Spanish news agency, that the home had become “a paradise” for the Matías family.

He said he himself had lovingly constructed the house in La Curra, a neighbourhood of Mas del Jutge, in a colonial style over three years.

Javi said he’d affixed ornamental amphoras and delicate clay stars beneath a sweeping arch.

Outside, there was little traffic in the cul-de-sac, meaning the boys could run around carefree with little perceptible danger.

The impending storm gathering overheard on 29 October was a very big danger, and so Victor closed his business early and picked up his boys from the nursey so that he could keep them safe and dry at home, as the rain fell harder and harder.

The force of the downpour became incredible, and soon the power was cut.

The brothers’ grandma, Antonia María Matías, a 72 year old cancer patient, told ABC Sevilla that she had called her son Victor at around 6pm and heard the brothers crying.

The water around them was rising all the time. But still, they were safe for now.

It may have been their haven, but the family home was also next to a lorry park.

Jonathan Perez, their next door neighbour, explained to us how this played a deadly role.

He said, “The father told us that there was a truck that hit the back of the house and the force of the water tore away everything.”

“Victor regained his footing and carried the boys in his arms. But then he realized he no longer had them. The water took everything in its path,” he explained.

Barbara Sastre, the boy’s aunt also told us at least one truck had sliced open the house in a blow that precipitated the boys and their dad being swept towards the nearby ravine.

The unnamed owner of the parking lot from where the trucks came told one newspaper they had not hit the family house. He insisted it was the strength of the water that did the fatal damage.

Jonathan, the neighbour, encapsulated the seething anger millions of Spaniards are feeling. Particularly, at the fact the official red alert sent to mobile phones came at 8pm – far too late.

“They were loving life and they hadn’t even started being people, they were three and five years old”, he said.

“With better coordination, better management, and an earlier alarm – even half an hour earlier – those kids could have been saved and those parents would not be going through hell.”

The whole neighbourhood in La Curra, stunned and shattered by the violence of the flooding, immediately began to search for the missing Izan and Rubén.

At least they did once the water had receded sufficiently for them to climb down from trees and clamber off their cars and try to re-orientate themselves.

They were helped by police officers from nearby Alicante, including a friend of Victor’s, who quickly arrived and began a desperate search.

But where to start?

Cars, bricks, bed frames had been carried hundreds of meters from where they once stood.

A team of firefighters from Mallorca and then Civil Protection volunteers from the island of Ibiza also came and scoured the most hard-to-reach areas.

Despite nearly two weeks of intensive daily searches, the brothers have not been found.

In the hours before everything changed, Marta – the mother of the boys – had started her late shift at the shop, safe in the knowledge their dad would be picking them up from school and taking them home.

In the early hours of the next morning, she was told her boys were gone.

Relatives say they can’t describe what Marta is experiencing.

The boy’s grandma, Antonia María, said her son Victor’s life had been destroyed – in her own words “turned to dust”.

As he was recovering in hospital, Victor took to sleeping with his boys’ blankets – salvaged from the ruins of their family home – resting on his face.

It is the closest he can be to them now.
