A 52-year-old man has become the third Las Vegas massacre survivor to die in a crash just weeks after the deadly mass shooting.

Roy McClellan was mowed down and killed in the hit and run while hitchhiking just outside of Las Vegas on State Route 160 in Pahrump, Nevada, on November 17.

His death occurred just over a month after California couple Dennis and Lorraine Carver were killed when their vehicle crashed outside their gated community in Riverside County, California bursting into flames, on October 16.

All three had survived the deadliest mass shooting in recent US history on October 1, when Stephen Paddock had opened fire from his Vegas hotel room on concertgoers at the Route 91 Harvest Music Festival below, leaving 58 dead and hundreds more injured.

Their losses now seem doubly cruel for the families of McClellan and the Carvers, who were just celebrating being reunited with the shooting victims after the near miss.

McClellan's wife Denise, of Las Vegas, told KSNV that she doesn't understand why both things had to happen to him.

'I don't understand why he wasn't taken at the shooting, but a month later he was taken this way,' Denise McClellan told the news station.

The 52-year-old was one of the survivors of the October 1 mass shooting that killed 58 innocent concertgoers at the Route 91 Harvest Music Festival in Las Vegas

Speaking to the network Denise, pictured with her husband, said she is consumed with anger that his lifeless body was just left on the side of the road

His wife said he was hitchhiking on State Route 160 in Pahrump when he was hit. She wrote on Facebook that prior to the fatal accident Roy had 'stormed off' after a fight with his friend

'I hope my husband found peace and he's safe now.'

The widow said the Vegas shooting was 'really messing' with her husband, and caused him to start going go therapy. She wrote on Facebook that prior to the fatal accident Roy had 'stormed off' after a fight with his friend.

Police have located the car thought to be involved with the accident, and charges are pending, according to KSNV.

Speaking to the network Denise said she is consumed with anger that her husband's lifeless body was just left on the side of the road.

'I'm angry. I feel that he was under the influence of something or drunk and didn't want to get caught, so he bailed and left my husband laying there in the street,' she said.

'He doesn't deserve that.'

The Carvers were at Route 91 Harvest music festival this month when Steven Paddock began shooting indiscriminately into the crowd from a hotel window

McClellan's family has started a GoFundMe to raise money for his funeral expenses. It had brought in nearly $2,500 by Saturday night.

Meanwhile, the Carver's 20-year-old daughter Brooke said her parents had grown even closer following the shooting.

During the onslaught, her father, 52, is said to have jumped on top of his wife, 53, to shield her from the bullets.

'After the shooting, they heard from all of the people they cared about most. They were so happy,' Brooke, told the Las Vegas Review Journal.

'We were so relieved when they got out of the shooting alive,' Brooke said. 'But I also think we've been given little pieces of them that we would've never gotten if the shooting hadn't happened right before they died.

'The last two weeks of their lives were really just spent living in the moment.'

The Carvers, of Riverside County, California. had been together for 22 years but only married in 2010 because they wanted their two daughters to be witnesses.

According to the couple's younger daughter, Madison, 16, there was a loud bang outside of her window on October 16.

When she ran down the street to see the source of the noise she saw her parents car engulfed in flames.

The pair died together, less than half a mile from their home.

A statement from the Riverside County Fire Department said their vehicle crashed into a metal gate outside their community at 10:50 p.m. on the 20000 block of Avenida De Arboles.

It took firefighters almost an hour to put out the flames.
