Some of the four people killed in a deadly Alabama shooting had "extensive criminal" histories and might have been killed in a "cowardly" murder-for-hire hit, authorities said Monday.
Gunfire erupted Saturday night as a "large group of peopleā were gathered outside the Hush Lounge in Birmingham, Alabamaās second largest city, officials there said.
Multiple shooters pulled up in a vehicle, got out and opened fire before they got back inside the vehicle and fled, authorities said.
