Online personality 'Boopac Shakur,' known for exposing alleged sexual predators, shot and killed in Michigan

A Michigan man who claimed to expose alleged child predators online for his thousands of social media followers was shot and killed after confronting two teenagers late Friday night, according to police.

Robert Wayne Lee, 40, would pose as a 15-year-old girl online to lure out and expose suspected pedophiles, the Oakland County sheriff's office said in a news release.

He published videos of his exploits to over 11,000 followers on Facebook and over 45,000 followers on Instagram. Some of those videos appear to show him engaging in violent confrontations with alleged predators.

Lee confronted two teenagers Friday night - a 17- and 18-year-old - at a restaurant in Pontiac. He accused one of being a pedophile and punched him, according to the police news release.

The teen who was punched pulled out a knife, and the other - suspected to be the 17-year-old - shot Lee several times with a pistol, according to police. He was taken to the hospital and later died of his injuries.

The suspects fled but were arrested Saturday afternoon, police say. The sheriff's office has not released their names.

Although Lee's "one-man crusade has led to the arrest and criminal charges being filed against several men," police said in the release, "he has also mistakenly identified someone as a sexual predator who was not."
