Vegas resident Brennan Stewart, 30, died while shielding his girlfriend, Gia Iantuono, from the crazed gunman’s bullets.
On Tuesday, she grieved on social media that she would not have survived without his heroics.
As the nation continues to come to grips with the senseless shooting, a song has been dedicated to all of the victims to encourage healing.
The song, “Dear Hate,” performed by Maren Morris and Vince Gill, features lyrics fitting for a time of national mourning.
“Dear hate, I saw you on the news today. Like a shock that takes my breath away, you fall like rain covering us in drops of paint. I'm afraid that we just might drown,” is one line from the song.
“Love's gonna conquer all. Gonna conquer all,” is another line from the tune.
Morris performed at the festival Saturday night and released the song, which she wrote more than two years ago following the church shooting in Charleston, S.C.
“I've had the song in my pocket for the last few years and I never knew when to release it," Morris told Rolling Stone. "I wanted to be precious with it because it is such a sensitive subject. It's just insane how relevant the message still is today."
