A Las Vegas man who survived the country music festival attack that left 58 people dead was killed earlier this month by a hit-and-run driver, leaving his widow reeling “in another dimension.”

Roy McClellan, 52, was killed Nov. 17 while hitchhiking on a highway west of Las Vegas in Pahrump after leaving the home of a friend he was helping with a house project. His wife, Denise McClellan, told the Las Vegas Review-Journal she had a horrible feeling in her gut that something was wrong after filing a missing persons report and seeing news coverage about the death of an unidentified man the following day.

“I read the words ’52-year-old man’ and ‘Pahrump,’” she told the newspaper. “And I just knew.”

Denise McClellan said she now feels like she’s in “another dimension” after her husband survived the deadliest mass shooting in modern US history only to be killed weeks later.

“My husband battled on a daily basis with depression, but that’s only one side of him,” she told the newspaper. “He was also someone who would give up his last dollar or give someone the shirt off his own back. That’s who he really was.”

Roy McClellan, according to the Nevada Highway Patrol, was walking illegally in the right lane of State Route 160 when a Chevrolet Camaro struck him. The driver took off and McClellan was later pronounced dead at the scene. It’s unclear why he was walking in the roadway, and the Clark County coroner’s office had not determined an official cause and manner of death as of Sunday, the Review-Journal reports.

The vehicle believed to be involved in the fatal crash was located one day after the accident, but police said a person of interest had not been charged as of Sunday.

“I just want some answers,” Denise McClellan told the newspaper. “I want to know why this person has not been arrested.”

Denise McClellan said her husband told her that the Oct. 1 shooting was “messing with his head” and that surviving the bloodbath during an outdoor music festival at the Mandalay Bay hotel casino before gunman Stephen Paddock took his own life had worsened his mental state.

“I believe that he’s happy now and he doesn’t have to battle his demons anymore,” she told the newspaper. “And I at least have that to hold onto.”

But Denise McClellan said she’s struggling to understand how tragedy has struck her again some seven weeks after surviving the shooting with her husband, who returned to the scene later to see if anyone needed a ride to safety.

“This isn’t what I wanted for him,” she told KSNV. “I don’t understand why he wasn’t taken at the shooting, but a month later he was taken this way. I hope my husband found peace and he’s safe now.”

An online fundraiser to offset funeral costs for McClellan’s family had eclipsed $3,800 as of Monday.

“All of your comments are so touching,” Denise McClellan wrote. “Yes I am having a hard time, it’s all so overwhelming and I know he’s in heaven [where] he will never feel sadness, pain, fear again. That is what gives me some comfort.”
