Tom, sorry to hear of your children's misfortune. Not sure what to do with the daughters "friends", but with regard to the boy's "friend", I would not say or do anything prior, but when he comes over, you could pull him aside and tell him "We have evidence that a certain individual has removed X,Y,Z games from our home. If that individual were to bring them back tomorrow, nothing will be said. If that individual doesn't bring them back, both the police and the individual's parents will be called". That allows him a out that will let him do the right thing. It also gives the course of action that he knows is coming if he doesn't. Even if you don't get the games back, perhaps it would be another life lesson. Good Luck.
On our end of things, been busy lately. I have a few cases left to go. Hopefully, I will be getting out in a timely manner. My son has a friend who is having a camp out/sleep over. His parents are in our Sunday School, good folks. I am supposed to go with him, but am on call. They live close to the hospital, so I may be able to do it....I hope for my son's sake. Of course, my back may regret it in the morning. So, no trains tonight, but I plan on it tomorrow.
Y'all have a blessed weekend.
Dennis
