UPPER MARLBORO, Md. (AP) — A former Maryland police officer convicted in a shooting that paralyzed a handcuffed suspect from the waist down was sentenced Thursday to five years in prison, far less time than prosecutors had requested.Former District Heights police Sgt. Johnnie Riley, 44, was sentenced in Prince George’s County Circuit Court. He could have faced up to 45 years in prison, and prosecutors asked for a 20-year sentence.Prosecutors say Riley shot a handcuffed man in the back in September 2012 after the man got out of a police cruiser and ran away. The injured man, Kalvin Kyle, was paralyzed from the waist down.
