Troublesome Teenagers

So what do you do?  My 15 y/o nephew, of whom I have legal custody, left the house on Friday under the guise of going to his grandfather's house to help him mow his yard.  When I went to pick him up on Sunday evening, his grandfather told me that he had never been there and that he was probably at his grandmother's house.  I went to grandma's house and she told me that he was off somewhere and that his aunt would be back with him any minute.  Sure enough, not three minutes later, his aunt came through the door, but when asked where David was, she said that he bolted around the back alley when he saw my car out front.  I couldn't think of a reason he would do that at the time except that maybe he had figured that I caught him in a lie and didn't want to face up to it.  (The lie being that he was supposed to be with his grandfather and wasn't.)  I went outside and called for him, but he didn't pop his head up.  It being after 9pm, I went ahead and left, telling his grandmother that if he showed up, to please let me know.  She said she would and so I left.  I stopped off at my son's house on the way home and told them what had happened.  They enlightened me to the fact that over the last couple of weeks, David had been talking about how he was bored at home, how he didn't like sharing a room with his cousin, didn't think he should have to wash his own laundry or ever cook for himself, and how he never had any privacy but was left alone at the apartment a lot (go figure?).  He had also complained that there wasn't enough food in the house and that he never got to see his grandmother and other family members.  This was the first I had heard of any of those things as David had never complained to me about anything except when was I getting his phone turned back on.  (His phone had been turned off as a consequence of misbehavior.)  Amazingly enough, a social worker from SRS called me on Monday to discuss a complaint their office had received on behalf of David which sited pretty much the same issues he had complained about to my son (and I'm sure to anyone else that would listen.)  I told the social worker about the unstable, chaotic situation he had come from prior to being placed in my custody.  That situation included living with a grandmother under Hospice care who also had custody of several of David's younger cousins.  David was associated with the local gang, who mostly lived on the same street as his grandmother.  Part of his experience with his little gang buddies led to David being convicted of felony burglary and placed on supervised probation.  I got custody of him a few months into his probation, which he completed successfully at the start of this summer.  Life at his grandmother's house meant there were no rules and no consequences for anything he did.  He stole from his grandmother and other family members, including breaking into his grandfather's house with one of his little gang buddies and stealing his grandfather's two rifles and a handgun.  He was caught trying to sell them a few days later, but continued to deny that he had anything to do with stealing them in the first place.  Anyhow, at grandma's, he could come and go as he pleased and he didn't answer to anyone...for anything.  At my house, he can't be trusted to be home alone so when my son is at work during the day, I take David to work with me.  When I do let him go somewhere, I have to know who he is with (as in I have to have met them!), where he will be, and what they will be doing.  He also has a set time when he has to be back home.  He hates this!  He has chores that he is expected to do, which his never seeming to find the time to do them is the reason his phone is shut off right now.  His only chores are to take the trash out at night and to unload the dishwasher some time during the day.  That's it.  Beyond that, he is expected to take care of his own laundry, which I taught him how to do when he came to live with me a year ago, and to pick up after himself.  If him and my son are at home alone, he is expected to look after himself, such as to make is own sandwich or ramen noodles or whatever, which he still expects someone else to do for him.  I told him that he could go to camp this summer if he wanted to and to just let me know where he would like to go, but he never did.  Our apartment complex has a very nice bi-level pool, which David has been to once this summer and that was only because I made him come with me one day.  He prefers to spend his time in the business center at the clubhouse where he can get online and talk to his friends.  I had to stop that when I found out that the friends he was chatting with were his former little gang buddies. 

So now, since my rules are too much for him (apparently), David had decided to run off.  I call his grandmother, sister, and grandfather multiple times a day to inquire as to whether he has popped his head up, but the answer is always the same:  no one has seen hide nor hair of him.  So today, I filed a runaway report with the police department.  I also contacted his former probation officer to see if she had any suggestions.  I also called the social worker for ideas.  The police entered his information into the NCIC and told me that if he came into contact with law enforcement for any reason, they would pick him up.  I know how that works tho....I'll be an old lady on my deathbed before that ever happens.  With his past trouble and gang affiliation, I'm afraid the police contact may very well be when they pull up on him lying dead in the street somewhere.  Then what?

Ideas?
