Mike Tyson told DJ Whoo Kid a story about when he was interviewed by a serial killer.

The former heavyweight boxing champ said this person would do interviews and “shoot” people in his spare time. The rogue journalist named Dale Hausner shot around 15 people and killed 9, according to Tyson. A few weeks after speaking with the killer, the FBI surrounded Tyson’s gym and questioned him on the matter. Tyson thought he did something wrong, but that was not the case. “FBI had blocked the gym off in a three block radius, and I’m saying ‘What did I do’? Whose a** did I grab?” Tyson said. The FBI presence scared the boxer, but it ended up being there because of the killer. The two touch on this topic around the 3:00 mark. Tyson also spoke with Howard Stern about the incident and said he would have never expected this journalist to be a killer. “He was a very frail, white guy,” Tyson stated. “It’s Ramadan, so I’m with this very righteous, Muslim dude with the Qu’aran and he was so nice. We took a picture.” The FBI found out about their meeting through the picture which was later posted to Hausner’s Facebook.
