Are there two versions of this movie?
I watched this movie when I was a kid, and it was my recollection that the girl took a fall off her bicycle after teasing Ronald. However, when I checked the YouTube excerpt at http://www.youtube.com/watch?v=tnlec1SuGTs, it shows him committing manslaughter. You could edit either way I think, and I know some of the ABC Movies of the Week have alternate versions in syndication.
Part of my recollection is that there's a later scene where the dead girl's brother comes to visit the new neighbors, tells them "he killed my sister", and Ronald startles in a way they hear him.
Anyone remember it the way I do?
BTW: Revived interest - in the Ugly Betty episode on 12/4/2008, titled "Bad Amanda", Amanda tells Betty that "Bad Ronald" snuck in and emptied their refrigerator. http://us.imdb.com/title/tt1263596
"Well, there it is."
