Watch: A victim's chilling Snapchat video captures moment gunman opened fire at Orlando nightclub

A victim's chilling video, which shows the moment a gunman opened fire at an Orlando nightclub in the early hours of Sunday morning, has emerged on Facebook.



Amanda Alvear (right) and her friend Mercedez Flores (left) are two of the 50 people killed in the mass shooting. Amanda shared video of her night out with Mercedez at Pulse nightclub on Snapchat. 

The first few clips, posted to her Snapchat story, show Alvear dancing and having fun with friends. The last clip captures Alvear’s reaction as gunfire rings out inside the club.

A video of the Snapchat clips was shared on Facebook by a Stichs Nbc, who says he is a friend of Alvear’s.

"Found out thru snapchat my friend Amanda Alvear was there at Pulse last night. Tried calling and texting and still haven’t gotten a reply,"  Stichs Nbc says in the video’s description.
