"He wasn't stopping, he just kept on shooting and shooting and shooting and just walking around," said witness Janiel Gonzalez.
Mateen, a U.S. citizen who grew up in New York, pledged his allegiance to ISIS and referenced the Boston Marathon bombers, according to Massachusetts State Police.
Investigators say he used an assault rifle to commit the killings.
Many people went to the scene Sunday night, holding signs and candles.
One woman was still waiting to to hear whether her friends are alive.
"I wish there was a way to stop it," said Xiomara Rodriguez.
