Got a pretty scary text that read… and if I contact police They will know and kill me. Hey your life is in danger, you need to get back to me asap if you wanna live, and if you think this is a joke then i am sorry for you because you wont live to see tomorrow. Anyway I want you to read this message very carefully, and keep the secret with you till further notice I feel very sorry for you. It is such a pity that this is how your life is going to end, but that’s only when you don’t comply with me . As you can see, there is no need to introduce myself to you because I don’t have anything personal with you, strictly business. I think I should tell you a little secret, I was paid to Eliminate you..But since my data page shows that you are innocent and I could make more profit out a double deal. I called my client back and ask him of your cell phone number which I didn’t tell him what I wanted to do with it and he gave it to me and I am using it to contact you now. As I am writing to you now my men are monitoring you and they are telling me everything about you. He told me that he wants your death to be sudden and painful as a pay back for a beef you both had. He had given us your names, photograph and all other necessary information we needed about you. so I sent my boys to track you down and they have carried out a very strict investigation on you. I am giving you a chance to live so you need to get back to me right now, and if you try acting smart or make an attempt to inform police, i am going to know and i will make this happen quick than expected... Get back to me as soon as you receive this!!!
