I have rec'vd several cards and phone messages from an officer with the special investigations unit wanting to set an appointment with me to Interview me at my house. He last left me a message stating if i did not respond to him he would come to my place of employement, then he left me a message stating that this has dragged on enough and if I don't meet with him this week he will have no choice but to review the information with the commonwealth's attorney. He then said that he is sure that I know what this is about, when really I don't. I don't know what my rights are, but I am rather intimidating by his messages and coming by my home for questioning? What do I do? I don't have any money to get a lawyer? And why is he not bringing me to the police station? Why won't he tell me what it is about? Special Invesitgations Unit???
