Authorities tell AL.com that the fatal double shooting started at Birmingham, Alabama's Aria Restaurant and Lounge early on Labor Day.
Then, as another car approached the Chevrolet Tahoe, it started firing rounds at it.
A spokeswoman for the University of Alabama at Birmingham Hospital told CNN that "shots were fired at a vehicle arriving at the emergency department with individuals believed to have been injured in an earlier off-site shooting."
"The shooter left the scene right away." Multiple gunfire sounded out like "iron pipes hitting," according to witnesses. A medical vehicle and a hospital window were both hit by gunfire.
900 block of Fifth Avenue North nightclub, according to Birmingham police officer Truman Fitzgerald, at least five people were shot.
According to the Jefferson County Coroner's Office, two of the victims—a 24-year-old lady from Center Point and a 33-year-old woman from Birmingham—were declared dead at the hospital. They were identified as 24-year-old Markiezia Atkins and 33-year-old Chaveda Willis.
Lockdown was imposed on the hospital.
On Sunday, the club was hosting a Labor Day Rehab Sunday event, according to the club's Instagram page. Only a five-minute drive separates the club from the hospital, which is Alabama's only Level 1 Trauma Center.
