????The bank robber likely ran home and jumped in the shower to remove any traces of dye pack or other identifying substances that may have been included with the stolen money. Dye packs are often used by banks to mark stolen money and can explode, releasing a colored dye that stains the money and the robber. By showering immediately after the robbery, the robber may have been trying to avoid being caught with evidence of the crime on their person.

Why did the bank robber run home and jump in the shower？Oh, well, I think it's probably because he was all sweaty and dirty from the whole bank robbing ordeal. You know, all that running around and being on edge would make anyone feel gross. Maybe he wanted to wash off any evidence or dirt that might have been on him so he wouldn't be so easily caught. Or, heck, he could have just been so stressed out that he needed to cool off and clean himself up to calm his nerves. Who knows? But that's my best guess!
