Multivehicle rearend

The title may sound somewhat obscene, but it's a rear-end accident involving more than 2 vehicles. Typical scenario is vehicle #3 hit vehicle #2 pushing it into vehicle #1. Seems pretty simple. . . . . until vehicle #2 says they were pushed into vehicle #1, and vehicle #3 says that vehicle #2 hit vehicle #1 first, then vehicle #3 hit vehicle #2. 

So here's a little hint, when you're thinking of lying to your insurance company and you're in vehicle #2. . . . if the damage to the front of your vehicle is significantly worse than the damage to the rear of your vehicle, chances are you rear ended the vehicle in front of your first, and then were hit by the vehicle behind you. So yes, the damage to the front is your fault. Moron.
