Letter from high school classmate in Prison?

I know I've caused you a lot of pain. But there's something I need from you. Something that will help me get out of here. I know this seems like a lot to ask for,but I need this and if you some how get this thing to me, I will leave you alone forever. Please get this to me soon. If not, when I'm out I will hunt you down and stalk you for what you did.

                                                              Your soon to be friend on the lam,

                                                                                   Joe Baker
