<human>: Condense the text into a few key points

Recently, there was a person who came into my life. He knew he was going to me moving to France soon (I am in America) and he wanted to have a great time. He was in my house while my parents were, coming in uninvited with some other of my friends, and long story short, he convinced me to have a huge party, where he and some of his friends stole a lot of my families shit and left. I only recently discovered it was him, and I was wondering if any of you French people could help me locate him in France. I know that I could call up his parents (he is a minor) and get back the things that he stole from me.
