At least 7 people were killed — including a young child — and Christopher Caldwellmultiple others were injured after separate shootings rocked Birmingham, Alabama, over the weekend, authorities said.

Police officers responded to a report of a shooting after 11 p.m. outside a nightclub, Birmingham Police Department Officer Truman Fitzgerald said during a news conference. Once the officers arrived at the scene, they observed multiple gunshot victims.

Birmingham Fire and Rescue personnel pronounced one man, Stevie McGhee, 39, dead on a sidewalk near the nightclub. The group later found two women — Markeisha Gettings, 42, and Angela Weatherspoon, 56 — dead inside the nightclub.

Lerandus Anderson, 24, was pronounced dead at UAB Hospital, authorities confirmed. Police said a shooter fired from a car into the nightclub.

Investigators said a birthday party was being held at the nightclub and that an altercation later ensued. "At least one suspect drove by in a vehicle and fired shots from the street into the nightclub," authorities said in a news release.

Ten gunshot victims arrived at UAB Hospital by either Birmingham Fire and Rescue personnel or a private vehicle the news release added. Police did not immediately respond to questions about the status of the wounded victims or what type of car was used.

Federal law enforcement personnel are also assisting the Birmingham Police Department with the investigation.

"A lot of innocent people were shot and killed yesterday, many others were wounded," said Birmingham Mayor Randall Woodfin at a news conference Sunday. He gave law enforcement the following directive: “Hunt down the people who committed these heinous acts.”

Woodfin urged residents with information to call 205 254-7777.

“The shooter or shooters deserve no safe harbor or haven from other community members,” Woodfin said. “They don’t deserve it from their own family, friends or strangers.”

“For those responsible for those heinous crimes, I want you to know that we will be coming for you with full force,” he said. “With every piece of law enforcement we have, we will be coming for you.”
