Former Del City police Capt. Randy Trent Harrison was sentenced Wednesday to four years in prison for fatally shooting an unarmed 18-year-old man following a 2012 police pursuit.

Harrison, 48, has been in the Oklahoma County jail since his first-degree manslaughter conviction in November.

District Judge Donald Deason went against the presentencing report recommendation that Harrison be given probation.

“Frankly, this presentencing investigation report is a joke. It said that Randy Harrison didn't have a drug problem. Randy Harrison was using hydrocodone the day that this occurred,” District Attorney David Prater said after sentencing.
