When the bullets started raining down on the crowd at a Las Vegas country music festival on Sunday, Sonny Melton's first reaction was to protect his wife.

"He saved my life," Heather Melton said. "He grabbed me from behind and started running when I felt him get shot in the back."

Sonny Melton, 29, a registered nurse from Tennessee, was soon pronounced dead, one of 59 people who were killed during the Route 91 Harvest Festival in Las Vegas on Sunday night.

Dozens of families are going through their own version of agony as Las Vegas officials process the massive crime scene and notify next of kin. Clark County Sheriff Joseph Lombardo said Monday that nearly 60 people were dead and another 489 injured.

Here is a look at some of the victims:

Chris Hazecomb, 44, of Camarillo, Calif, had shielded his best friend's wife after the shooting started. The graduate of Thousand Oaks High School, a sports junkie and country music fan, soon became the 59th victim in the shooting.

With a priest by her side, Maryanne said her goodbyes.

"You don't expect your kid to go before you go," she said Tuesday after returning to her Camarillo home. "He was good to everybody. He'd go out on the limb for everybody."

The couple married in June 2016, according to the wedding website The Knot.

"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. "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."

For Adrian Murfitt, the country music festival was a group celebration after a successful fishing season off the Alaskan coast.

His sister, Shannon Gothard, said Murfitt was every bit the Anchorage native — he played hockey "since he was just a little tot" and would spend months at sea as a commercial fisherman. Gothard said her brother was even talking about going in with a friend to buy their own boat.

That all came to an end Sunday night when a man opened fire and Murfitt, 35, was shot in the neck while he stood near the stage. Gothard said the family was reeling, and she struggled to describe the kind of person he was.

"He was my brother, so of course I thought he was an arrogant little cuss," she said, struggling to laugh. "But only I can say that cause he's my brother. He had this big, jovial, goofy laugh. He'd always try to do the right thing. He had a big heart."
