Defense tries to discredit psychologist who talked with Richard Allen | Delphi murders trial Day 11

On Day 11 of the Delphi murders trial, a prison psychologist told jurors about alleged confessions made by Richard Allen that the prosecution says provide details only the killer would know.

Dr. Monica Wala, who treated Allen while he was at Westville Correctional Facility, told jurors she met almost daily with Allen and heard him confess to the murders of Abby Williams and Libby German several times. One of the confessions, she said, was very detailed, as she wrote in her clinical notes.

After Wala recounted her notes of the confession to the jury, defense attorneys got her to acknowledge she diagnosed Allen with "serious mental illness" and that he had an abrupt occurrence of psychotic behavior around the time he confessed.

The jury also heard of Wala's longtime fascination with the Delphi murders case and that she talked to Allen about what people had said about him online and in podcasts about the case.
