Other mistake: Legendary wrestler Antonino Rocca makes a cameo appearance in the movie. He is, as correctly listed in the closing credits, one of the "Funeral Attendants" together with Michael Weil. However in the opening credits he was specifically billed as the Funeral Director, which is Ronald Willoughby's role as correctly listed in the end credits. (00:00:50 - 01:45:15)
Continuity mistake: When Brooke Shields yells "Mommy said that you had to come home right this instant", there's a long lock of hair in front of her left shoulder, which disappears at the cut. (00:06:20)
Answer: Mrs. Tredoni, the church housekeeper is the murderer. Although, it's left unclear if Alice helped with the murders at all.

Thanks. I could never figure out if it was one or the other.
