Caller kept calling asking if I was alone, that I needed to go straight to a hospital. When I would ask why, the call would get a lot of interference. This happened over 3 calls. He was telling me it was very serious, but I never could find out why, on last call it was clear and I said I would turn number to police. He said it was very important but If I didn't want to know he wouldn't tell me and hung up, and wouldn't answer anymore.
