Italians have begun burying some of their dead from the Genoa motorway bridge collapse, holding funerals in the victims’ home towns.

Several angry families rebuffed the offer of a state funeral and the cardinal of Naples was merciless in his condemnation of negligence by Italian officials.

Saturday has been declared a national day of mourning in Italy and will include a state funeral in the industrial port city for those who plunged to their deaths as the 45-metre (150ft) tall Morandi Bridge gave way on Tuesday.

But many of those who lost loved ones declined to participate in the state funeral.

Some cited the need to bid farewell in private while others blamed the loss of at least 38 lives on those responsible for the bridge’s safety.

Anger and sadness erupted at the funeral on Friday for four men in their twenties, all friends from the Naples seaside suburb of Torre del Greco, whose lives were lost as they drove over the bridge heading for a holiday in Spain.

“You can’t, you mustn’t die for negligence! For carelessness! For irresponsibility! For superficiality!” said Naples cardinal Crescenzio Sepe in his homily.

Finding the cause of the bridge’s collapse during a driving rainstorm might take weeks or months to determine.

But Genoa prosecutors say they are focusing their investigation into possible criminal blame on design flaws or inadequate maintenance on the heavily used bridge, which was completed in 1967 and linked two high-speed motorways in the city.

“My boy and the others suffered murder,” said Roberto Battiloro, whose 29-year-old son, a videographer, was one of the four friends who died.

“They died an absurd, blameless death just for going on holiday.”

His voice shaking with anger, Mr Battiloro said his son was the “victim of a cruel fate, but also of whoever didn’t think that on that bridge could be the children of those who are despairing today”.

“I have died inside, but I have to find the clarity of mind to say that four boys were not number 27, number 28, etc (on the victims’ list), but people who loved life,” Mr Battiloro declared.

Other private funerals were held in Piedmont and elsewhere in Italy.

Survivors were shocked at how they escaped with their lives.

Davide Capello, 33, a firefighter and football player, was driving alone on the bridge when his Volkswagen Tiguan and the road it was on plunged to the ground.

He immediately understood that the structure was collapsing, watching in shock as a car in front of him “disappeared in darkness”.

“It came down, everything, the world came down,” he said, adding that he managed to walk away physically unharmed but psychologically traumatised.

His car plunged nose first, then stopped with a crash, air bags releasing all around him.

He said he saw only grey as concrete dust covered the windows.

Mr Capello used the touchscreen phone in the car to call colleagues at the Savona dispatch centre, who sent help.

He then called his girlfriend and his father, a retired firefighter, who told him to get out of the car immediately for fear that it would destabilise or something heavy would fall on top of it.

Since neither the car’s windows nor its doors would budge, he unclipped his seat belt and climbed out through a hole in the rear of the car that was blasted open by the crash.

Outside, he said, “there was an unreal silence” – destroyed vehicles and piles of broken concrete, but no signs of life, no cries for help.

Rescue workers then helped him climb down from the rubble.

“I got out with my own legs,” said Mr Capello, who plays for a Serie C club in Liguria. “I don’t know if anyone else managed to. I was saved by a miracle.”

“The car protected me. Besides God, the car also did its job,” Mr Capello said.

On Thursday, prosecutors said as many as 20 people could still be missing in the bridge collapse, but cautioned that some people initially reported as unaccounted for might be on holiday and had not yet contacted their families.

Civil protection department officials said on Friday there might only be five people missing, but the exact number was fluctuating.

Excavators have begun clearing large sections of the collapsed bridge.

Rescuers have been tunnelling through tons of jagged steel and concrete blocks to look inside crushed vehicles.

Several vehicles, abandoned by their fleeing occupants on the intact ends of the bridge, were gingerly removed on Friday.

Among them was a green food delivery truck, which – its windscreen wipers swishing, its gear stick in reverse – had halted only a few metres from the jagged edge of the abyss.

For many, the truck at the brink became a symbol of destiny and survival.

Motorway workers, directed by firefighters, backed it off the bridge and into a nearby tunnel.

Authorities are worried about the stability of large remaining sections of the bridge, which was built over or adjacent to several apartment buildings.

Hundreds of residents in those buildings have been evacuated – and there is no guarantee they will ever return to those homes.

Emergency workers also want to quickly remove the tons of debris that fell into the dry riverbed under the bridge so it does not create a dam that floods the rest of the city if heavy rains fall again.
