dont give up so easy baby
Since everyone knows she is there you cannot get away. The only way you could get a lenient punishment is if she actually attacked you. You will have to think hard and make it look like she took the first step. You don't want to make wounds on yourself that looks like she stabbed you. They will find out she did not. So maybe she drugged you and tied you to the bed and started force feeding you antifreeze when you woke up. That does mean you need a little more stuff than you provided but who doesn't have these things?
So you make ligature marks on yourself, actually tying yourself to the bed would be ideal. You need one arm to get loose and that hand will probably be more injured. And then the other ties you could simply undo. Make it look like that happened. Mix a drink with a strong sedative and drink it and leave the glass there. Then force feed yourself the antifreeze. In bed. How you get her prints on the bottle I don't know. Any blood transfer is bad.
So this is what happened. You served yourself a drink and went to the bathroom. She spiked your drink. You thought at first it was the booze kicking in then realizing something was wrong. You wake up tied to the bed. She feeds you the antifreeze. At first you think she just wants something kinky then you realize she is actually trying to kill you. That psychotic bitch. You struggle and you finally get loose, get hold of the bottle and then you fall to the floor, unconscious.
After a little while you drag yourself half way out of the apartment where you pass out again.
A neighbor calls the cops and an ambulance.
You say it is self defence and that you are traumatized. You act traumatized. You have nightmares and flashbacks. You will probably be saved from the antifreeze poisoning.
Make the details look right. Don't make it too complicated.
It obvious that she was at your place and since you don't have anything to clean up with you're not going to hide it.
Change your clothes so if little Tommy son of a bitch saw you through the window he'll think he saw someone else.
Set fire to the apartment. Stab yourself in the stomach with the shard of glass, paying attention to the angle so it looks like another person did it, dial 911, and put the phone in her hand. Then chloroform yourself.
When you wake up and the cops start asking questions it's time for the best acting performance of your life. Next time plan your murders out in advance.
Or pack a bag, take her keys, and whatever cash you can find, and drive her car to Mexico.
Need to get rid of the body first. They wont come searching your place until the Amber alert is out. So that gives you 24 hrs. Take the body way out in the middle of nowhere. Burn it, then bury it really deep. Get her car and drive it as far away as possible, burn it. Story goes that she drove home after the movie and you didnt see her since. Bleach and clean your apartment.
"You will probably be saved from the antifreeze poisoning"
That doesn't sound reasurring...besides where did I get antifreeze at? Am I expected to siphon it from my car? And I really don't want a death on my record...
Do it again SensitiveSoul and don't fuck it up...
