340 FINALLY SOLVED, SAY FBI

I HOPE YOU ARE HAVING LOTS OF FUN IN TRYING TO CATCH ME 
THAT WASNT ME ON THE TV SHOW 
WHICH BRINGS UP A POINT ABOUT ME 
I AM NOT AFRAID OF THE GAS CHAMBER 
BECAUSE IT WILL SEND ME TO PARADICE ALL THE SOONER 
BECAUSE I NOW HAVE ENOUGH SLAVES TO WORK FOR ME 
WHERE EVERYONE ELSE HAS NOTHING WHEN THEY REACH PARADICE 
SO THEY ARE AFRAID OF DEATH 
I AM NOT AFRAID BECAUSE I KNOW THAT MY NEW 
LIFE WILL BE AN EASY ONE IN PARADICE 
LIFE IS DEATH
