I can't be sue but it looks like it could be a knife pendant. Something like these:

I notice in pics 6 and 7 she is wearing a scarf. Even though I think the one she used was the one EO was wearing it is possible that AB did bring one of her own. I don't think the scarf used to strangle Elizabeth was silk as in the actual expensive fabric but rather a silky material. I know I have some and so do my daughters. You can get some nice ones at AC Moore the craft store for fairly cheap but sometimes you can get ones that look vey high quality. I doubt that LE was reading labels for fiber content when it was listed that a silk scarf was found at the scene.
As I was looking for knife pendants I noticed that they are mostly labeled as chef knife pendants. Although I don't think that is who most of them are purchased by. I have seen handcuffs and other things like that at Hot Topic so I wouldn't be surprised if they carried a knife and axe ones.
Mornin everbody..i missed alot over the last day or so..the pendant,,it definately looks like a meat clever to me...i also been thinking on "how a girl ABs size overpowered and killed a girl about the same size" i read elizabeth was 5'2" and 108 lbs,,thats comperable to a 15 Y/O girl,,(i think anyway),,here's my thot...JMO ofcorse..AB lured elizabeth to the woods,and seen she wore the scarf..then decided to strangle her, to keep blood off herself or whatever reason..but when she grabbed her,she freaked out,and adrinalin kicked in,and AB didn't get the job done..so, she pulls out her knife,as she previously planned to use it anyway, and stabs elizabeth,,which instantly brings her to her knees,,then, she can easily get behind her and grab her hair,and slit her throat,,sorry if i sound morbid,,but i'm trying to understand this,as it eats at me every day...
1 more thing,,maybe 2.. the news said they have her on 24 hr suicide watch,,could it possibly be that she is beginning to see the impact of what she did? maybe there realy is some little bit of her left, I think her ATTY will probably use this to get her sentance reduced.,however,,i still think she should spend the rest of her life in prison..i also think she very well might have had help,as i seriously dont think she could do all that she's reported doing in the time span givin..JMO,,again,,JMO.
