That first message came at 8:01 p.m. after Kazinskaya and a friend had bought last-minute tickets to see Soviet-era rock group "Picnic."
"I heard shooting, I realized it wasn't squibs. At first I thought maybe it's a special effect but then no, it doesn't sound like that. So I poked my friend and she said 'people, get up, let's run'."
At 8:08 p.m., she wrote three messages on her phone in quick succession:
"Please ring the police."
"Crocus City Hall."
"Shooting."
Kazinskaya and her friend had managed to escape the hall but found themselves still trapped inside the building.
The shooting stopped, but there was now another danger: fire.
The gunmen had used gasoline to set the huge concert hall ablaze and the two friends took refuge in a toilet.
They tried half a dozen times to get out but were forced to keep retreating.
At 8:23 p.m., she left a four-second audio message. She thought it would be her last.
"I love you. Goodbye"
Then, eight minutes later, at 8:31 p.m., another message:
"I'm alive. I'm in an ambulance. I got out. Thank you."
KAZINSKAYA: "I didn't realize I was safe. I had only two thoughts. First, I need first aid because I can't breathe. My lungs were burning, and I was having an asthma attack. And the second thought was I have to get as far away from the building as I can, get behind the cars as fast as possible because if something happens I'm a target, I'm in white. Those two thoughts. And somehow I made my way forward."
Returning home, Kazinskaya says she just "hugged everyone."
She says she draws comfort from the amount of support she has received... but that it will be a long time before she goes to clubs or big concerts again.
