Last week, attorneys for special ed student Marshawn Pitts released the security video below, which shows Pitts being beaten by Christopher Lloyd, a police officer in Dolton, Illinois who was working security at the school. Pitts' attorneys say Lloyd administered the beating because Pitts hadn't tucked in his shirt, as required by the school's dress code.

When the video first emerged last week, the Dolton police department refused to release Lloyd's name. With good reason. Lloyd is in jail in Indiana. He was arrested last month for raping an Indiana woman at knife point. He had also threatened the woman weeks earlier, but apparently wasn't arrested or disciplined for it.

But it gets worse. Lloyd was also fired last year from another suburban Chicago police department . . . for killing his ex-wife's husband in front of their children. The town of Robbins fired Lloyd after the February 2008 shooting, but Chicago police bought Lloyd's claim that the shooting was self-defense, so he was never charged. That enabled Lloyd to find work at the Dalton police department 11 months later.

According to a lawsuit filed by Lloyd's ex-wife, autopsy reports contradict the police investigation. The autopsy shows that Lloyd shot the man 24 times. When contacted by the Chicago Tribune, a spokesman from Chicago PD said details of the department's investigation of the shooting "could not immediately be found."
