He pleaded guilty to first-degree murder because his friend, accomplice Antwun Parker, 16, was killed. His time in custody included stays in the Oklahoma County jail and juvenile facilities.
His deal required him to stay out of further trouble. Prosecutors could ask the judge to order Ingram to serve up to a life term in prison. They likely will seek a shorter stay. Ingram is no longer eligible for juvenile detention.
Ersland is appealing his murder conviction.
Prosecutors alleged Ersland was in the wrong because he shot the second robber five more times after knocking him unconscious with a shot to the head. Prosecutors also pointed out at trial that the second robber did not have a gun and was on the floor when he was shot the last five times.
Jurors agreed with prosecutors. They rejected Ersland's claim that he was justified in his actions because he was defending himself and two female employees. His pharmacy license expired after he went to prison.
