Rogel Lazaro Aguilera-Mederos (pictured), 23, on Friday was charged with 40 criminal counts for allegedly causing a massive pileup in Colorado that killed four

A Texas truck driver accused of causing a 28-car chain-reaction crash near Denver last week that killed four people and injured four others was charged on Friday with 40 criminal counts, including vehicular homicide.

Police in Lakewood, Colorado, said they arrested Cuban national Rogel Lazaro Aguilera-Mederos, 23, after he lost control of his tractor-trailer truck during the evening rush hour on April 25 and caused a pileup on Interstate 70 that involved at least 28 vehicles.

The district attorney for Jefferson County, where the crash took place, charged Aguilera-Mederos with 40 count, including four counts of vehicular homicide, six of first degree assault and 24 of attempted first-degree assault.

Aguilera-Mederos is being held in jail on a $400,000 bond. He is due back in court for a preliminary hearing on July 11.

The tractor-trailer, which was carrying lumber, rammed into several cars, causing the multi-vehicle crash that became a raging inferno, authorities said. The four men who died were all single occupants in their vehicles, according to a local TV station.

They were identified on Sunday as Doyle Harrison, 61; William Bailey, 67; Miguel Angel Lamas Arrellano, 24; and Stanley Politano, 69.

LIST OF CHARGES: Aguilera-Mederos faces the following 40 counts: Six counts of first-degree assault 24 counts of attempted first-degree assault Four counts of vehicular homicide by reckless driving Two counts of vehicular assault by reckless driving One count of reckless driving Two counts of violent crime causing death or serious bodily injury One count of violent crime using a weapon Advertisement

Arrellano is survived by his mother and brother, who recognized his sibling's charred car in the pileup, reported 9News.

The 24-year-old's family and friends described him as a happy and humble person.

A GoFundMe page started by a friend to help Arrellano's family with his funeral expenses had raised more than $12,250 by Friday evening.

'The carnage was significant,' police spokesman Ty Countryman said at the time. 'Just unbelievable.'

There was no initial indication that Aguilera-Mederos intentionally caused the crash, or that he was under the influence of drugs or alcohol, Countryman added.

Aguilera-Mederos told police his brakes had failed, but cell phone video from a witness showed his truck veering across several lanes of traffic and forcing another vehicle off the road before the crash, according to an arrest warrant affidavit.

Rob Corry, a lawyer for Aguilera-Mederos, said last week that the crash was an accident caused by equipment malfunction.

'This is a massive unprecedented overreach by the prosecution ... on a vehicle accident,' Corry told reporters on Friday.

Meanwhile, the suspect's wife, Nailan gonzalez, has been busy raising money to help pay for her husband's defense through Facebook.

Aguilera-Mederos was visited by his wife on Monday. She subsequently wrote on the Facebook fundraising page: 'Rogel is innocent and we all know it.'

'Thanks for all the support [we have] received. Until now let us remain united and praying for him. This will be the only page that will be raising funds. If you see any more, please report them ... Grateful to God and to each of you.'

In three days, $20,102 had been donated towards legal expenses. By Friday evening, however, it appears the fundraiser had been taken down.

In a Facebook post written in Spanish and translated into English on Friday, Gonzalez decried the 40 charges brought against her husband.

'Oh my God. I will die from this one. 40 counts and there is no bail,' she said. 'I can only ask that you continue to support us. This makes me realize that life can change you in a matter of seconds. God give me the strength to face this whole situation.'

She has switched her fundraising efforts on behalf of her jailed husband from Facebook to a cash app and a cellphone account.

González previously wrote that her husband said he was being treated unfairly but did not specify in what way.

'Babe, please give thanks on my part because unfortunately I can not do it. God is with me. It is unfair what they are doing to me, but I never thought that I would have [the] world out there supporting me,' the Spanish written statement from Aguilera-Mederos said via his wife's post.

'I never imagined that there would be so many people defending me. In these moments my best lawyers have been all those who have given me that great support, and those who have and continue to pray for me. I wish so much to come out to be able to give my thanks. There is no money to pay for everything they have done. I truly feel too grateful. Without your support none of this is possible.'
