My son is 12 and in middle school. I received a phone call from the principle stating that my son had tried to spend $50 in the school lunch line and when asked about it he walked away and threw the money away. When confronted he came up with a story about being paid by an older kid. I took him to the police station to have them help us get to the bottom of this. Evidently he is stealing from me and his stepfather and has been for awhile. The police said that there is nothing they can do. This is the second time he has been caught stealing from me. He did so about 3 years ago and I made him take a theft prevention course. I don't know what else to do. Does anyone have any advice?
