605-277-9451 in Aberdeen SD started calling at 745 am Monday 3/24/14. Didn't answer, they called right back. On third call I picked up and said 'stop calling me'. Male trying to sound official said "'mam this is about a legal investigation and we need to send someone to your house, do you understand". I said stop calling and hung up. Got an immediate call back, which I did not answer. Calls then stopped. No messages left.
