No, it was Brenda, and she bought it at Mervyns. After Brenda and the girls left to go drinking, Damon killed his little girl and wrapped the body up in the plastic fitted mattress protector.
When the pizza gang comes over that night, the mode is somber because they help clean up the evidence, and move the body into Damon's van.
See Kim, anyone can spin a story when you get to make up facts and speculate wildly.
There is no evidence of this "plastic fitted mattress protector from walmart." or even from Mervyns. -- And no evidence that anyone remotely connnect to the case has bought one.
You are absolutely correct. The plastic sheet theory can/could address "why" there wasn't more blood in the MH. Where could the sheet be? Maybe with her missing pajamas? I think we're all assuming that the MH is where she died. (cept for those who think she died in the VD masterbedroom which is just another theory)I could say that DW really was drunk and "he's" the one who fell on top of her and passed out.... I see a lot of speculating or trying to fill in the blanks with educated guesses. Is there a problem doing it? I don't think so...I know some lurkers got annoyed hearing the wilder theories..
