Thanks to Making A Murderer, the 2005 murder of Teresa Halbach and subsequent conviction of Steven Avery and his (then) 16-year-old nephew Brendan Dassey have returned to the spotlight in Wisconsin, and have since seen the attention stretch far beyond state lines. In the wake of the wildly popular Netflix docu-series, some have become skeptical about the way the Manitowoc County Sheriff’s Department handled the investigation—even causing some to petition for the pair to be retried or flat out pardoned.

While most people pushing for Avery and Dassey’s release have expressed their grievances in the form of online petitions, Facebook statuses, and drunken arguments with friends about a key chain, Brendan Dassey’s half brother Brad Dassey decided to utilize a longstanding vehicle for expressing social unrest to challenge the convictions: rap.

On Sunday, the self-proclaimed “indie Christian rapper” released “They Didn’t Do It” on his YouTube and SoundCloud pages. The song—which the Manitowoc emcee says he made over 10 straight hours of writing and recording—claims injustice was “slammed in the face of two innocent people” before repeatedly suggesting “they didn’t do it.” As the debate of Avery and Dassey’s innocence intensifies (at least until the next season of House Of Cards comes out), listen to Brad Dassey’s new track.
