A fourth person, an innocent bystander, who was also inside the store was struck by the gunfire as well. Police said it's unclear at this time if the bystander was shot by the suspects or the customer who fired on the suspects. 

After the suspects left the store, a fifth suspect, who was waiting in a car, fled the scene with the suspects, who then went to a nearby hospital where three of the suspects received medical treatment. 

Officials said the innocent bystander who was struck, was taken to the hospital and is said to be in stable condition. 

As for the suspects, police said one of the suspects is in critical condition while the two other suspects are in stable condition. 

Police said they also believe they have the driver of the vehicle in custody as well.
