Brendan Dassey's Brother: I'm Taking My 'Making a Murderer' Rap to Prison

Brendan Dassey is now getting a stronger defense than anything he got in court -- in the form of a rap about the "Making a Murderer" case, written by his half brother.

Brad Dassey is an up and coming Christian rapper who cut the track 2 days ago, after he got pissed about Brendan and Steven Avery's prosecution while watching the Netflix series.

"They Didn't Do It" is loaded with jabs at the authorities like, "Not a fair trial, not a fair game. Whole thing's wack, just a lying shame."

It might not be award-winning, but it's from the heart. Brad says he worked on it for 10 straight hours. This is personal for him on several levels -- he's been hounded because of his last name, and says he got fired from his DJ gig when Brendan was convicted.
