Man called my cell phone looking for someone else and I told him I was not the person he was looking for.  He did not believe me and threatned me when I told him to stop calling.  He kept calling me and then he said he was a terroist and if I did not come up with $5,000 in two days he would kill me.  I asked him what he wanted and he said the names of people I know who use drugs.  I think he may have been a telemarketer because the person who had this number before me would get calls from mail order pharmacies.  I could not believe what this guy was saying to me.  I called the police and changed my number.  Hopefully he does not do this to anyone else!
