Check the brake lights switch's plastic bumper.
The brake lights circuit is one of the few _always hot_ circuits in the car; the horn is another.
If that little plastic bumper fails your brake lights are always on. (In my crx, it failed at work and I had to jump start the car because the battery was completely dead.)
Take Care,

PS,
look for:
-always hot wires that are shorted to ground (maybe in the area your car was hit; wires pinched in crush zone)
-any aftermarket accessories wired always hot in your car? (instead of into ACC hot)
