Maybe a trip tour down at juvy will open his eyes. I do think the dad needs to step up and take over, maybe being thier with dad more involved will make a diffrence. Remember this though. Moving doesn't take the gangster out of the kid, The kid just finds a new gangster group to join. I live in a new area, and have heard many families say that that's the reason they moved out here was to get their kids out of gangs or ganster areas. But the kids just found thier kind and made new gangs. We have graffiti up the butt. But not the shottings. Luckily they clean up the graffiti quickly. This isn't just for gangsters. It's for band, cheerleading, football, etc. Your kid will fit in where he thinks he belongs. So maybe moving in with you and a visit to juvy and then what you expect from him, also maybe seeing a counsler might help him to open up with his feelings. He must be going through something deeper then we want to believe. Sometimes it only takes a strickter parent. sometimes it's depression issues, and sometimes it's just trying to fit in. Help him before it's to late. Sometimes a policeman can get them to open their eyes. Don't allow him to do anything extra until he proves himself to you, good grades means going out with friends. Be the hard --- until he figures it out.
Good Luck I hope you find him before he gets to far gone. J.
