I'Ve Been Framed

My DNA was planted at a crime scene in an apartment that I truthfully have never been. My fingerprints were found on the murder weapon, a Bowie knife that was a gift from a long lost friend. Buried in storage for decades is where that knife had been. Until now, for me that Bowie knife was long forgotten. I don't know nor have I ever known the victim or any of the victim's past or present relations. I'm now the prime suspect in this investigation and I don't have a very good alibi to give them. "Where were you at the time this murder happened?" the detective asked me during my interrigation. "I was at home alone," I answered, "as I often am." The detective then asked me the following question, "Can your presence at that time be substantiated by anyone?" "None that I can think of presently," I responded feeling broken. I was read my Miranda rights and I'm now in the system, but I swear, I've been framed. I Am Innocent." * The above hasn't really happened to me, but one day it did occur to me that due to my lifestyle which I live very solitary, that I could be a sociopath's perfect patsie, since very few ever eye witness that I truly may be at my home all alone with just my cats for company, and my felines can't attest to my presence unfortunately. *
