Las Vegas massacre: Portraits of the victims

At least 59 people were killed when a gunman opened fire late Sunday at a Las Vegas concert. Families and loved ones of those killed, or of the more than 520 injured, have spoken to media outlets or taken to social media to express their condolences.

Lisa Romero-Muniz and Sonny Melton were among the victims. Melton, of Big Sandy, Tenn., was protecting his wife when a gunman aiming from the 32nd floor of a Las Vegas hotel-casino unleashed a hail of bullets on an outdoor country music festival below, his family told Fox affiliate WZTV.

"At this point, I'm in complete disbelief and despair," the man's wife, Heather Gulish Melton, told the station in a statement Monday.

"I don't know what to say. Sonny was the most kind-hearted, loving man I have ever met," Melton said. "He saved my life and lost his."

Melton, 29, was a registered nurse who worked at Jackson-Madison County General Hospital in Jackson, Tenn., according to his Facebook profile.

On Friday night, Melton posted on the social media site that he was attending the Route 91 Harvest Festival in Las Vegas with his wife, an orthopaedic surgeon.

The couple worked at the same hospital and married in 2016.

"We were the couple that never should have met, fallen in love or had a future together....but life is funny and we believe God brought us together as soul mates," read their wedding page on the website The Knot. "We have shared amazing times together and nearly unbearable heartaches but through it all we have grown stronger in our love for each other and our families."

Lisa Romero-Muniz, who also was killed in the shooting, worked as a secretary at Miyamura High School in Gallup, N.M. A school official confirmed to Fox News that Romero died at the concert.

A Canadian man, identified as 23-year-old Jordan McIldoon, also died in the shooting, according to multiple media reports. He was days away from his 24th birthday. A fellow concertgoer, Heather Gooze, wrote on her Facebook page that McIldoon died in her arms, CBC News reported Monday.

The man's parents, who confirmed their son's death to the news outlet, said McIldoon attended the concert with his girlfriend and had planned to return home on Monday.

"We only had one child," they said. "We just don't know what to do."

Alaska native Adrian Murfitt, 35, died during the concert, a family member said Monday. Murfitt worked as a fisherman, and went to Vegas to attend the concert to "treat himself to something nice and fun," his sister told The Associated Press.
