He went to grand jury & pleaded the 5th. Well the investigator called me & stated the grand jury wanted to speak to me about his charge. I never received a subpeona or anything just got a call at 6;30 yesterday evening. So when I get there this morning they say they need to speak with me about a possesion charge for myself. Never have I been arrested for this charge & had nothing in my possesion. He told them specifically on the day he was arrested that I had nothing to do with that. What should I do?
