Florida mass shooting: Video shows crowd just before 3 gunmen opened fire

Twenty-three people were shot, including two fatally, early Sunday morning.

Police investigating the mass shooting rampage in Miami Dade-County, Florida, are reviewing videos like this one, which shows partygoers gathered outside a banquet hall just before the three gunmen opened fire. The video, obtained by ABC affiliate WPLG in Miami, shows the victims duck and crawl for cover after shots rang out early Sunday at the El Mula Banquet Hall in Hialeah, where a local rapper was celebrating his birthday. One man appeared to use his body to block a woman from the bullets as they hid between cars. Twenty-three people were shot, including two fatally, in what Miami-Dade County Commissioner Keon Hardemon called an act of domestic terrorism.
