Here is the link to the story about the three boys dying in the trunk.

also note that no one could say why the bloodhounds did not alert to the trunk right where the boys were last seen - personally I think someone put them in the trunk, an older teenager, but that is just my theory and not proven. I know that people love to use Bloodhounds but I'll take my Coonhound and truth be told, my coonhound that is now 11 years old and has much experience is really good at picking up fresh scent trails and he is my number one dog - every handler that works more than one dog, and I like using up to 4 dogs, quickly learns that each hound has its good traits - what the dog can do or can't do - and a person needs to use a dog that will pick up only the freshest trail every time and ignore the old ones - not something every dog will do. And maybe the bloodhounds sniffed around the car and was led away by the handler and the handler made a mistake, not the dog. Hard to tell.
