When Detective Thorne first finds the box at a murder scene, there is a candle on top containing a child's finger. Later in the movie it is revealed to be his own finger as a child and that he is trapped in hell. However, at the time the initial finger is found, he has not yet opened the box and therefore has not yet condemned himself to hell.
When the guy is sitting in the ice cream truck telling the story of Terry, to his left is a sticker with the Rugrats logo and an image of a Tommy Pickles ice cream bar above it. After the flashback to the story he's telling, it cuts back to him, and now the Rugrats logo is nearly scribbled out and red circles have been drawn on the ice cream bar image.
