Officials in Birmingham, Alabama, pleaded Monday with members of the public for information leading to arrests in a weekend mass shooting that killed four people and injured more than a dozen others, announcing rewards of up to $100,000. Police Chief Scott Thurmond said at a news conference that police are still sifting through tips. Five of the injured victims remain in the hospital, he said. The FBI is offering a $50,000 reward, and Crime Stoppers is offering $50,000, officials said. Tipsters can remain anonymous, they said. Authorities have still made no arrests after Saturday's shooting killed four people and left 17 others injured in what police described as a targeted “hit” by multiple shooters who opened fire outside a popular nightspot in Birmingham's Five Points South district. The shooting rocked an area of restaurants and bars that is often bustling on weekend nights. The mass shooting, one of several this year in the city, unnerved residents and left officials at home and beyond pleading for help to both solve the crime and address the broader problem of gun violence. “The priority is to find these shooters and get them off our streets,” Birmingham Mayor Randall Woodfin said a day after the shooting. The shooting occurred on the sidewalk and street outside Hush, a lounge in the entertainment district, where blood stains were still visible on the sidewalk outside the venue on Sunday morning.
