PORTSMOUTH, Va. (WVEC) -- The Virginia Court of Appeals has denied Stephen D. Rankin's appeal of his voluntary manslaughter conviction for the shooting death of 18-year-old William Chapman II.

Rankin was a Portsmouth Police officer when he fatally shot Chapman in 2015, after responding to a shoplifting call at a Walmart. Witnesses said a struggle ensued before the shooting, and at Rankin's trial, attorneys argued over whether deadly force should have been used.

A jury found Rankin guilty of voluntary manslaughter in August 2016.

The jury recommended to a judge that Rankin serve two and a half years in prison. Prosecutors had sought a maximum sentence of 10 years.

The judge agreed with the jury's recommendation, and sentenced Rankin to 2.5 years in prison.
