On Sept. 29, Robert Wayne Lee, 40, who was known as Boopac Shakur, was at a Pontiac restaurant when he confronted two teenage males, ages 17 and 18, and accused one of being a pedophile, according to the Detroit Free Press.
The teenagers reportedly fled the restaurant, but police were able to apprehend them.
Lee was transported to a nearby hospital, where he was pronounced dead from his injuries, officials said.
Oakland County Sheriff Michael Bouchard said the teenager Lee "was mostly focused on and talking to and became heated with was not the individual who shot him."
Bouchard claimed that "it was the other person on the opposite side of the table,” according to WJBK.
The Detroit Free Press reported the gunman was allegedly the 17-year-old boy.
Authorities have not released the names of the two suspects and the case has been turned over to prosecutors for potential charges.
Lee was affiliated with Dads Against Predators and would pose online as a 15-year-old girl to expose suspected offenders on Facebook and Instagram, the Free Press reported.
