In the ad Angela Wagner wrote up to sell the vehicle she claims all the seat covers are leather. If true, that's going to make blood clean up pretty hard. You could clean the surface of the seat but the stitching and on the leather below the stitching... not so good. The rugs and below the rugs on the actual floor... internal surfaces of doors, deep in where any screws attach the doors... stupidity is using a vehicle like that to commit murder in the first place. I was generous and supposed there were some brains involved... I assumed a pickup truck, using only the bed of the pickup truck to transport the actual killers, was used. Later, you could clean that with bleach and a high powered hose. Still, you might miss some blood that way. But, I never dreamed anyone was idiot enough to use a vehicle like the one they did. And, not just one idiot but here, you have four of them.
