Four separate shootings have led to the accusation of the Birmingham nightclub massacre suspect of killing others.

The suspect accused of shooting outside a Birmingham nightclub in September has now been charged with multiple killings in different shootings this year.

On Wednesday, the Birmingham Police Department announced that Damien McDaniel, currently in police custody, was charged with capital murder for the July 13 mass shooting that resulted in the deaths of four people and injuries to 10 others. McDaniel is 22 years old.

Birmingham Police Chief Scott Thurmond stated that he believed the Sept. 21 mass shooting in Birmingham, where four people were killed and at least 17 others were wounded, was a "hit" and that the suspects were paid to open fire. McDaniel was already connected to this incident.

The Sept. 21 massacre occurred near the University of Alabama at Birmingham, while both shootings happened outside of nightclubs.

McDaniel, already linked to two mass shootings, is now suspected in three additional fatal shootings that occurred on three different days in August and September.

Police believe that McDaniel is responsible for the deaths of 11 people and the injuries of 29 others across five separate incidents.

Capital murder charges were also filed against Hatarius Woods, 27, in connection with the July mass shooting. Although other shooters were involved in the Sept. 21 massacre, the investigation into the shooting is still ongoing.

On Wednesday, during a press conference, officer Truman Fitzgerald stated that Woods and McDaniel were responsible for approximately 30% of homicides in Birmingham from July to September.

"Officer Truman Fitzgerald stated at a press conference on Wednesday that the individuals involved in the crime began in July and continued until September. He emphasized that a small group of criminals are responsible for the crime and tarnishing the reputation of Birmingham."

Woodfin, the mayor of Birmingham, has publicly addressed the city's crime problem and urged state legislators to tackle the issue rather than just increasing the number of police officers on the streets.

"Despite increasing the number of police officers on our streets, individuals are still legally allowed to drive around with these types of guns, the mayor stated in a YouTube video on Tuesday. If I were a betting man, I would assume the residents of Birmingham have had enough of this and want to see more gun safety laws in place that protect people in Birmingham, but this needs to come from a higher authority."
