My dad is who? (A Marilyn Manson story)

Before I was born my dad had left me and my older brother chad with our mom. chad died in a car crash when I was only 7 years old. After my brother died my mom changed a lot so did I. When chad died I started to listen to more and more heavy metal, goth rock all kinds of stuff to keep my mind off of it. my mom didn't seem to care anymore as I got older she seemed to just slip away more. she would never tell me about my dad all I know is his name is Brian.
