Ex-District Heights officer to be sentenced for shooting handcuffed suspect in the back The former District Heights police officer who was found guilty of first-degree assault for shooting a handcuffed suspect in the back is scheduled to be sentenced in Prince George's County Circuit Court on Thursday morning. Johnnie Riley, 44, appeared for sentencing on Sept. 2 but his hearing was postponed after authorities said he tried to attack prosecutors during courtroom proceedings. Riley's bond was revoked after several sheriff's deputies had to subdue Riley and clear the courtroom following the outburst. Riley's case stems from a September 2012 incident in which the then-sergeant took Calvin Kyle, 28, into custody on suspicion of riding a stolen motorcycle, according to authorities. After Kyle was detained, he was handcuffed and placed into a police cruiser but tried to flee, prosecutors said. As Kyle ran from the scene, officials said, Riley chased him and fired his gun. The bullet struck Kyle in the back and left him paralyzed from the waist down. During his trial, Riley said he did not remember that Kyle was handcuffed and worried he'd be ambushed during the incident, according to a report from WJLA (Channel 7). Riley faces a maximum sentence of more than 45 years in prison as he was also convicted of second-degree assault, misconduct in office and use of a handgun in commission of a crime of violence, prosecutors said.
