My name is Clayton I am 20 I currently do not live with my Mother but she needs help.

My Mother has been with him for 6-7 years the Boyfriend has a drug problem my Mother as well but she wants to stop doing it and get away from Him, She keeps going back because He has the money to supply the drugs.

He beats Her constantly and plays tricks on Her making her think She is crazy He threatens to murder her and that certain People want Her dead and if it wasn't for Him she would be shot dead, my Mother told me his Lawyer has been calling and asking if He has been doing certain types of drugs and he denies it. Apparently He knows a lot "higher up People" and that if Our family does anything that He would really screw over Our family in anyway he could Law wise and Criminal wise,

What I want to know is:

Q:What actions can i take without making My self get into trouble with whoever he knows?

Q:Is it okay/Can i get into trouble if i call his Lawyer and tell Him what he is doing and has done for the past 6-7 years/The drugs He does/Supply's?

Q:Is there anyway i can do this without having my entire family brought into this?
