Terribly sad news out of HPD — the Metro cop who was involved in the agency’s first fatal shooting has committed suicide.

Officer R.L. Harrington had been no-billed by a grand jury in relation to the incident, in which he shot and killed a knife-wielding man and injured a passer-by near the Rice campus.

“We’re confident that Officer Harrington did exactly what he was supposed to do,” Metro police chief Tom Lambert said after the no-billing.

An unidentified male’s body was discovered at 3:45 a.m. September 5 in a car in the 9300 block of Richmond.

“Patrol officers responded to a shooting-in-progress call and found the victim sitting in the driver’s seat of his vehicle with a gunshot wound to the head,” HPD said at the time.

HPD spokesman Victor Senties tells Hair Balls, “The case has been closed out as a suicide.”

Metro spokeswoman Raequel Roberts referred all questions on the matter to HPD. Metro and the bystander who was shot offered wildly divergent descriptions of the event and its aftermath.
