Hmm..
So I was thinkin' about the kick in the neck. Let's suppose they were both standing, which is probably how they were when she was stabbed. 'Kay, she's stabbed several times. So, to get him off and away from her, she kicks him. Supposing that she was shorter than him, if not dramatically so which is often the case of girl's heights compared to guys', then to kick him in the neck she'd have to kick really high. Which, could happen. But. If she's sitting there having all these recently inflicted stabs and is bleeding heavily (as one could safely assume), I doubt she'd be able to kick up high enough to his neck, without stumbling or tripping, yet having enough momentum (if that's even the word?) or speed and strength to give him a blow in the neck. Say she did do all that though. Even with a blunt steal toed boot, it wouldn't but a hole in the guys neck. It'd probably just send him sprawling out on the ground with a bruise to remember. Either that or a snapped neck.
Or, okay. say she was laying on the ground. He came at her. She kicks him in the neck. Still. Why would she be wearing some big frickin' clod hoppers around her house? So you were coming over and maybe you were gonna go outside. That could be likely. But I've seen a picture of Faris, and from what she's wearing in the picture, she doesn't look like she'd be wearing some big sharp high heels. Which, I could see maybe make a hole. But why would she go out with a friend in those anyway? But, nonetheless, if she was laying on the floor she'd have more balance to be able to kick him. But even with "heavy treads" as you said before, that would probably more leave a scrape acrossed his neck from where they kicked by. Depending on the angle. But if she kicked him, in the neck, with the end of the toe of the shoe which is wear the shoe and the neck would connect after a kick, do you think having heavy tread is going to matter? No. Tread is on the bottom. You don't kick with the bottom of of your shoe. But, if you did which is possible I suppose, it'd be like a big flat surface like: ( ____ ) <-that. On his neck. Even with heavy treads, it'd be a flat surface kicking in the neck. Would that cause a gaping hole in someone's neck? No. Maybe a tiny little hole from where one little tread pierced him, but they'd be like 1/8 of an inch deep, if that. So possibly he could have these tiny little 1/8 deep holes here and there from where a tread cut him. But that still wouldn't get him anywhere near a gaping hole.
Also, yeah with the end of the letter, there should be ranom characters here and there from falling on the keyboard. But say she didn't, fell to the side and off the chair or something, chances are still that her hand would have fell on it, or atleast dragged over it when she fell. So, that seems really unlikely.
But also Trig, on your little journey for information, I have some last names, first names, and some pictures.
