Based on a real-life case, this involved two families who are next-door neighbors and best friends. They have a picnic or barbecue, and the teenage daughter of one of the families asks if she can camp out with the other neighbors’ daughter in a tent set up in their fenced-in back yard. Prior to that, the girls have a run-in with the neighborhood bad boy and his buddies, but no one thinks anymore of it~till later. Sometime during the night, the girl at whose house they’re staying goes indoors, perhaps because it’s more comfortable there or because she has argued with the other girl. I don’t recall the reason.
In the morning, when the outdoor girl hasn’t come to the house for breakfast, they check on her and are shocked to find her dead, lying on her back, a pillow over her face. The other teen girl notices that there is a bandana lying next to the body, an article of clothing she believes belongs to the tough boy. This incident causes a fierce division between these former best friends, especially when the police point to the son of the host family as being a likely candidate for the crime, claiming he sexually attacked the girl then murdered her.
Later, it is shown that the police are so confident in their choice of murderer that they make errors in collecting evidence, either mislabelling evidence, leaving items behind, and, it is discovered later, allowing some of it to be destroyed before it can be examined again! I don’t recall the outcome of the case, but I think the accused boy’s name was cleared. I don’t think the police ever focused on the boys who had accosted the girls earlier.
I think I saw this on Lifetime, but it might have been on some other network station, such as USA. It’s definitely a made-for-television movie. I might recognize the name if I saw it, and I’ve been checking listings for many months till asking about it. Frustratingly, I can’t recall who plays any of the parents, but I seem to recall that they are "TV name" actors, fairly well-known to audiences. I would estimate this film being from the mid- to late 1990s, but it could have been made in the 2000s. It would be difficult to judge from its style. I’m generally good at tracking down movies, but I’ve used many keywords and phrases to search the real-life case and the movie. I thought I’d toss this out to see how quickly it will be identified.
Moment of Truth: Murder or Memory? (1994) (TV)
A young man, while under hypnosis, confesses to a brutal murder. But did he really do it?
"Very good film showing how the police can go overboard when things look bad for a suspect. A murder is committed during an overnight party at a home and a boy is the prime suspect after he becomes confused over his actions after the party was over. He couldn’t remember whether or not he did the crime; leading to his arrest, the ostracization of the family, and a big court action. Do attorneys really go home with their clients and have dinner with them?"….as per ‘helpless dancer’ poster on IMDB.
