Turning Someone in for Selling Food Stamps?

I have a son who is 37 and does nothing but smoke weed and drinks all the time. He works and makes good money. He went to prison in 2003 because he was on crack. He got out and was living with my youngest son who is married. My son threw him out of his home because he got back on crack. He moved in with me because he had no where else to live. He was still drinking. He did finally get a place to live. He ended up seeing a woman who was married and has two children. She is finally divorced but she needs to get out of his life for good. She and my son started doing their weed and drinking all the time. The woman stays at my son's home every weekend. They smoke pot in front of the two little girls and she also drinks and drives. I also know that she has the little ones in her car and they are not always fastened in their car seats. She was in a wreck 2 years ago and she was drunk. Her mother had her children. She came to my home to call her mother but didn't tell that she was drunk. A few days later she shows up again with a nice car that her mom bought her. The woman gets food stamps and is selling them. She calls my husband and wants him to buy the food stamps from her. I won't buy them. She is selling them for drugs and alcohol. I also called D.F.C.S. on her last month to turn her in. I had talked to a woman who gave me an 800 number. I almost didn't do that. One of my friends had called me long distance and I had let her know what is going on with my son. She had let me know that she would have already turned the woman in. I don't know what happened to my son but I'm not giving up until she is gone. He also had asked his step-dad for help in getting rid of the woman. If he won't help then it is up to me to do it. How long does an investigation last until the woman is caught? I called the 800 no. on Nov. 25. My son also does not pay his rent and is getting evicted from his home. How long does an investigation take before something is done? Sorry if this is so long. This has really been hard on me.
