Update: A mother to a 12-year-old boy is now the third person to die from the latest mass shooting in Miami over the weekend. The 32-year-old had been in a coma with a bullet lodged in her head. She was one of 23 people gunned down outside a Miami banquet hall that was hosting an album release party. Two men died on scene and 13 others remain hospitalized three in critical condition. Police are searching for three gunmen, and are offering a $130-thousand dollar reward for their arrest. The get-away vehicle was found in a canal and reported stolen.

(MIAMI) — Police investigating the mass shooting rampage in Miami Dade-County, Florida, are reviewing videos like this one, which shows party-goers 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.

The gunmen waited outside of the banquet hall for about 40 minutes and then opened fire on patrons as they left, Miami-Dade Police Director Freddy Ramirez told ABC News on Sunday. Some patrons returned fire, Ramirez said, and over 100 shell casings were found at the scene.

Police on Monday released surveillance video of the three gunmen exiting a white Nissan Pathfinder at the scene. The suspects ran back to the car about 10 seconds later, once the carnage was over.

Police said the car — which was stolen several weeks ago — was recovered Monday evening, submerged in a canal.

The three suspects remain at large.

Authorities said they believe the shooting was motivated by an “ongoing rivalry” between two groups.
