Here's my question. If a fairly large amount of human blood was spilled/bled/whatever onto a wooden floor (not sealed, if it's important, but pretty nonporous), and left open to the air (and humidty/temperature changes - the door of the room is left open to the outside), how long after it's left there will it be possible to get a DNA result?
I'm not looking for 'courts will accept this', just if it will come out well enough to confirm suspicions of who might have bled on said floor.
There's copious amounts, if it matters, and three different people bled on the floor. There might be some mixing of the blood, but if they took samples from several different places, they'd be able to get an uncontaminated sample.
The floor hasn't been swept or washed in about 2 years, and the room had been sealed up for that time, so it's probably pretty dusty, if that helps.
I'm hoping it will be a week or so, maybe less... but who knows?
