I thought of freezing time and stabbing them in the temple so they'd drop dead immediately upon time being unfrozen. That way I'd be able have an undeniable alibi (maybe in the middle of a work day, so my work records would show that I was there and my coworkers could vouch for me being there), and the people present would see an alive man inexplicably drop dead and when the stab wound was found, they wouldn't automatically point fingers at somene who wasn't even present at the time.
I'd have to make sure to wear gloves to avoid fingerprints and walk there in shoes that don't belong to me so there would be no random footprints in a dirt patch or anything. With time frozen, it doesn't matter how long it took to walk there. And I'd have to wear clothes that don't belong to me because I imagine I'd have to discard of bloody clothes. Maybe I could stop in some store on the way there and steal an outfit. With the gloves, I'd leave no fingerprints, and with time frozen, the cameras wouldn't see me. Then again, I don't even know if he'd bleed if his blood flow was frozen in time. I'd also have to wear maybe a shower cap or something so my hairs wouldn't fall out.
Mines not very creative but that's all I can think of. haha.
Anything to add or argue?
