I need to brainstorm. Okay, lets say a married couple have separate, but identical guns. The wife shoots someone. Ballistics shows the bullet from the victim came from her gun. But she throws her gloves away and gets her coat cleaned, so there's no gunpowder residue. Then she says her husband used her gun and shot the guy. There were no witnesses. I thought about the police finding powder residue in her car, which is possible according to everything I've read. But she could say her husband drove it. I've got the cops trying to trick her by saying they have a video of her with the gun, but she wasn't buying it. I need suggestions. Lets brainstorm.
