Authorities ask public to help identify gunmen in deadly Miami-area shootings

Authorities called on the public to help identify gunmen who indiscriminately sprayed bullets into crowds at two Miami-area venues over the weekend, killing a total of three people. Two people died and over 20 others were wounded early Sunday morning during a shooting outside a concert in Miami-Dade County, about a day after a drive-by shooting killed one person and injured six in Miami's Wynwood arts district.

In northwest Miami-Dade County, police said three hooded men armed with assault rifles and handguns jumped out of a white Nissan Pathfinder and opened fire, CBS News correspondent Manuel Bojorquez reports. Police on Monday said investigators believe the shooting was the result of an ongoing rivalry between two groups. "This type of gun violence has to stop. Every weekend it's the same thing," said the police director of Miami-Dade County, Alfredo "Freddy" Ramirez III, whose officers were hunting down the suspects in Sunday's shooting that took place shortly after midnight.
