Witness of a bank robbery

That day i was playing games while my mom deposit her money. Many people were there. Then the ciminals went on a rampage and killed 3 people. All of the customers were terrified and they were panic. Then the robbers shouted out loud that no-one was allowed to go out or they will kill everybody. I think the robbers don't know how to use the guns because they didn't there guns striaght and when they shoot they miss alot. Then the robbers started taking the money. I think I recognized one of the robbers. I think he is my friend's uncle because he look very familiar. He's the one who shoot the customers. One of the robbers was tall and he's very hairy and the one that wait beside the door wear glasses and he has big eyes. That's all i know.
