Prosecutors instead read a transcript of Prince's prior testimony to jurors.
In it, Prince said he and Baker planned to rob Waldenville, but it was Baker who shot and robbed the lawman of two bank bags when he turned and appeared to be reaching for his gun.
Prince testified previously that both men approached Waldenville as he walked to the bank but Prince stopped about five feet short of the lawman out of fear.
“I got too close to him,” Prince said. “If I snatch these bags I'm dead.”
Baker's attorney, Craig Hoehns argued at trial that Baker was innocent because he wasn't there the night Waldenville was ambushed.
“This man is not guilty because he didn't do it,” Hoehns said in his closing argument. “They got the wrong guy.”
Hoehns told jurors that Prince and another man shot and robbed Waldenville. Prince, he said, turned in Baker because Baker knew about the robbery and stole money from Prince.
Hoehns also said Prince couldn't be trusted because he testified that a third man participated in the shooting and robbery of Waldenville by tipping them off as the security guard exited the restaurant.
But charges against Diante Keon Douglas, 18, of Midwest City, were dropped after Prince said he lied when he implicated Douglas.
District Attorney David Prater declined to comment.
Prince's mother refused to speak with reporters about her son, who has an eighth-grade education, records show.
