Tupac Shakur and The Notorious B.I.G are hip hop icons. Their murders in 1996 and 1997 left fans reeling and asking many questions - mainly, who killed them, A man who knows the answer is the man who was charged with reopening and reinvestigating the case, Greg Kading.

I got to chat to Greg when he was in Dublin about why people are still interested in this case, what it’s like working on a case like this, how it took over his life and the new Netflix series based on his investigation, "Unsolved: The Murders of Tupac and The Notorious B.I.G"
