“No matter what happens between us I just want the truth known ya feel me?” Morrison wrote.

After Morrison refused to testify about the letter Friday, House ruled for prosecutors on a motion to keep the letter out of evidence. Moore’s fiancée provided the Post-Dispatch with a copy of it.

The judge allowed an audio recording of a Feb. 20 interview Moore’s lawyer had with Morrison to be played in court Friday. In the recording, Morrison said he lied at Moore’s trial about plotting with Moore to kill Crump. He also claimed police and prosecutors helped him concoct the story for the trial.

Moore has spent 18 years in prison for convictions of robbery and drug dealing, court records say.

Moore told the judge in court Friday that he was not guilty of the charges and that he wouldn’t be “stupid enough” to kill someone in a park in front of 300 people at a family reunion.

“I swear on the soul of my kids that I’m not guilty of these charges,” Moore told the judge.
