Deliberate mistake: The lake that the girls splash about in is very shallow, as they easily stand and play in it. Roberta does a head-first dive from a high tree, into it. There's no chance she wouldn't have hurt herself. (00:32:35)
Deliberate mistake: When Roberta copies the article about her mothers death, the machine obviously copies the page too fast. It copies it immediately, yet in the 1970's copy printers were incredibly slow.
Answer: There are two different men named Peter. In the shot of the newspaper while Roberta is reading the article, it states that the driver of the pickup truck was Peter Norris (00:41:35). Then Sam finds the article about 12 year old Jonathan Simms and his mother, Beverly Ann, so we know that "Crazy Pete" is Peter Simms (00:43:00).
