Answer:
b. The shooter fired the gun close to her forehead.
Step-by-step explanation:
If gunpowder residue was found around the wound it tells investigators that the shooter fired the gun close to her forehead. Gunpowder is expelled from a gun when it is fired and only travels a small distance, therefore wherever gunpowder is found means that the gun was fired very close to that area. Experts say that gunpowder residue travels about 3-5ft from where the gun was fired at the very farthest distance.
