Denise was with her husband at the Route 91 Harvest Festival, sharing her account of that fateful day.
"I don't understand why he wasn't taken at the shooting, but a month later he was taken this way", McClellan's widow, Denise, told KSNV-TV.
McClellan and his wife made it out safely when a gunman opened fire at the Route 91 Harvest music festival on October 1, killing 58 people, his widow said.
The massacre was the deadliest mass shooting in American history, with 58 people murdered and 500 others injured. "He doesn't deserve that", said Denise.
As round after round of bullets were unloaded in the crowd below the Mandalay Bay, Denise and Roy McLennan ran for their lives, with Roy McLennan stopping to help people along the way.
"Those who knew him know he had his battles but also knew he had a big heart", she wrote.
A survivor of the horrific Las Vegas shooting has passed away in another unfortunate tragedy... She said her husband stopped to help some people as they fled. "Roy also loved helping people and would literally give the shirt off his back", Denise McClure wrote on Facebook.
The driver who struck Roy McClellan has been found and charges are pending.
A California couple, Dennis and Lorraine Carver, also survived the shooting and were killed in a auto crash near their home in Riverside on October 16, according to the Las Vegas Review-Journal. "I hope my husband found peace and he's safe now".
A massive fire erupted after the wreck, the California Highway Patrol said. The auto crashed into a metal intercom speaker. The auto struck another brick column, rolled onto its side and caught fire. Police do not suspect foul play.
Roy McClellan is the third Las Vegas shooting survivor to die shortly after that incident in recent weeks.
