A man was arrested in a deadly shooting along A1A in Fort Lauderdale early Tuesday, authorities said. When police got to the scene, they found a vehicle that had crashed into the seawall. Meanwhile, "several other officers arrived on scene and located a subject fitting the description provided," according to authorities. A Ring doorbell camera video obtained by NBC6 showed a shirtless man who appeared to be armed going door-to-door in the Fort Lauderdale neighborhood shortly after 2:30 a.m. Police confirmed that the man was arrested on unrelated charges, but haven't confirmed that he was the gunman.
