Looking back at issue #36 of Fangoria I notice on the body count list #12 is Mom: drowned in bathtub. We all know that the scene where Trish finds her mother dead in the bathtub-- which did make it to the box set in the alternate ending-- never made it to the final cut of the film as per director Joe Zito's request.
For the longest time it was greatly debated what actually happened to her and there were rumors of her demise and a lot of people hinted towards Mrs. Jarvis being found in the bathtub dead (which a snippet of that scene can be seen in a trailer, but no Mrs. Jarvis).

According to this article, the movie was still being edited as it was written so it makes sense why her death is on the list. We all know that she dies, just in later articles it was always written that she died offscreen. Also notice that it says that Terri was killed while riding her bike. It also says that Tina was "defenstrated," which literally means "to throw someone out of a window." Odd use of words, and no I didn't look it up. I actually knew the meaning from a Wesley Willis song.
