When the shots began, Norman Casiano fled to a bathroom near the back of Pulse nightclub and huddled with others inside a bathroom stall. The gunman entered the bathroom shortly after.

In an emotional Facebook video posted from his hospital bed the morning after the shooting, Casiano described his injuries.

鈥淚鈥檓 fine,鈥 he says. 鈥淚 was shot four times in my back. Thankfully they just went straight through.鈥

鈥淭he best thing we can do is stay happy, remember these people for the good they did in life, and keep praying for those of us that are in the hospital.鈥

PATIENCE CARTER

Patience Carter, 20, also hid inside a bathroom stall during the shooting. Speaking at a news conference outside Florida Orlando Hospital, Carter described how the gunman spoke to the hostages.

鈥淗e asked if there are any black people in here; I was too afraid to answer,鈥 said Carter, who is African-American. 鈥淏ut there was an African-American man in the stall where most of my body was, and he said, 鈥榊es, there are about six or seven of us.鈥 And the gunman responded by saying, 鈥榊ou know, I don鈥檛 have a problem with black people. This is about my country. You guys have suffered enough.鈥欌

Carter has since posted about her recovery , detailing her state of mind in a post titled 鈥淭ruth.鈥

鈥淎s long as the majority of the world that sends their love and support knows the truth. As long as the strong members of the LGBT community know the truth. As long as I know the truth ... I can find some peace to heal. I can find some peace to learn how to walk again. I can find some peace to want to live on,鈥 she wrote.
