Just sorta thinking about the car. And the fact that there doesn't seem to exactly be a lot of time for BK to have stripped off a protective suit outside the house before getting in the car.
If I was BK and didn't plan to wear a protective suit (disposable ones can be noisy and would he want to spend time outside the house to take it off?), what steps could/would I take to prep my car & myself?
Vans are easy for me to toe off once I get outside the house. I can leave a pair of mens slip on sandals outside my car on the ground to change into or even drop them off outside the house as I enter. Leave a trash bag outside the car or tucked in my pocket to toss them in before I get in the car.
Disposable gloves--either I can double glove so I can pull off the outer ones and shove them in a pocket/bag before I exit and need to touch the slider door handle or I wear one pair and leave the slider door open enough that I can slip out or stick my arm/leg through the opening and push it open without my bare hands touching the handle.
My exterior car door handle--either I can assume my hands won't have blood on them because I will have already taken my gloves off, or if I'm paranoid I could wrap it in duct tape, cling wrap, etc.
Inside the car (going from manufacturer photos of the inside of a standard model):
the steering wheel--if my bloody gloves are still on or I'm worried I might have blood on my sleeves that could transfer, I would have already put a small trash bag over it and secured it with tape around the steering column, but not so tight that I can't operate my turn signal or turn on my headlights
starting the car--many levels of that year's Elantra have a push button start. If I'm worried about transfer, I'm taping some plastic over it. If I have a key start, before I cover the wheel I'm inserting the key and leaving it in the ignition until after I take the key off. A loose enough bag will let me manipulate it. Maybe I even have a remote starter installed after I bought it and can start it with my key fob.
gear shift and parking brake-- bags over them.
car seat--I'm getting some cheap vinyl/plasticky elastic car seat cover that I can toss later.
gas/brake pedal--I'm not too worried here, I already took my Vans off. But if I'm paranoid about my pants or socks dripping, I'm covering them with bags and securing them with tape.
floor of the driver's side--cheap floor mat I don't mind pitching or taping plastic tarp down (less likely, too easy to rip down and slippery when I"m trying to get in and out).
seatbelt--no way am I putting it on. There is no good way to cover it entirely, esp up at the top where it's going to retract back in while I'm in the house....and no good way to protect the buckle and lock and still have them work. We already know he had no problem driving w/o a seatbelt as we saw when he got pulled over in August in Moscow at 11:40 pm w/o a seatbelt. Anyway, I just killed 4 people, so I'm not real worried about following the rules of the road right now.
Honestly my biggest concern if I'm a tall guy like BK is my legs brushing the underside of the driver's side foot well, or my arms/legs brushing against the inside of the door. Tape and tarp time. I'll have to be careful and precise here so that it doesn't risk getting caught in the door and torn down. I might even make sure to cover that gap between the driver's seat and the part next to it where the parking brake/gear shift is so that any hairs that are on me don't drop off and hide in there.
My main problems in making sure my car is protected are where can I do all this taping without being seen/noticed and making sure I tape things on securely enough (the joys of tape in the winter time) but also taping them loosely enough that movement won't immediately rip them down or hamper my ability to steer/change gears/close the door/etc.
I can put on the seat cover and spare floor mat without drawing suspicion back at the apartment. Heck, I can even slip the bags over the pedals while I put in the spare mat during the day. No one would really notice me slipping bags over the steering wheel and gear stick/parking brake (if I plan to use it) when I get in my car to leave that night. But clearly I'm not taping up the pieces of tarp to the inside of the door or the walls of the foot well in my apartment lot, not even late at night. Maybe this accounts for the gap in time between when I left my apartment and when I parked at the house and entered--I find some deserted area, dead end road, or whatever and tape up my plastic tarp pieces that I cut roughly to size earlier in the day. Heck, I can even put a spare mat on the passenger floor just in case my bag with my shoes has any blood on the outside of it.
Now I just drive off and find somewhere to stop, pull off my outer layers and bag them, clean up, and remove the all the bags and coverings. I've got the rest of the night to ditch them and the knife. I can spend the next few days with some Goo-Gone to get any adhesive residue off the interior, vacuuming to make sure there are no hairs, etc.
Is this over the top and too detailed? This is a guy who was sorting trash into baggies in the middle of the night when he was arrested. I think he'd have no problem with it. If he's worried about people seeing him buying several plastic tarps, he can space it out over a few trips and pay cash. Or he can take his own kitchen trash bags and cut them open at the seams to use as tarps.
