HHM....Well first I would follow my target around to find out a little about him/her, mostly his sleeping habits and wether or not the house he/she lives in has any other inhabitnts the could cause some kind of problem.
I would plan the night of the murder weeks in advance and be sure to plan a bon fire the day after.
I would make sure to wear gloves, hair net, mask, thick socks, tight fitting pants, tight fitting long sleeved shirt, and I would make sure that most if not all the following would be a dark blue, not black. Black would actually outline my figure and make me easier to spot.
Seeing as how I know when and how long he/she sleeps I would go to the house during the middle of their sleep to ensure they are less likely to wake. I will also be sure there is a new moon so there will be little to no moon light.
If I am driving I will be sure to park the car 2 or three streets down from my target. I would then make my to the house.
When I got there I would make my decision of which door to break into depending on the houses surroundings. i.e. In a remote location any door will do, but if it is in a culdesac (however you spell that) and is surrounded by houses, I would choose the door where I would be less likely to be seen. i.e. not the side where there are hardcore partying stay up all night college students.
After picking the lock I would take off my boots and enter the house. I would stick close to the walls where the floor is strong and less likely to creek. I obviously do not know which room he/she is in I would probably spend a lot of time looking for the target.
I would open the door(s) slowly at first and if it creeked I would open it quickly to keep it from making noise.
I would then most likely smother the person with a pillow or cloth, after which I will take it with me.
I would leave and be sure to lock the door on my way out.
Then In the morning I will wake up early, shred/rip all the clothes I was wearing that night, and do the same to the murder rag/pillow.
After which I would set the fire pit for my bonfire with the shredded items scattered/woven in between the layers of wood and cover it all in a lil gas/lighter fluid.
Then just as people begin to show up I will set the evidence ablaze.
THE END
