A court filing by the defense team for Richard Allen suggests they may call Kegan Kline as a witness in the Delphi murders case.

The motion by Allen’s attorneys asks the judge to order Kline transported to court from the prison where he is currently serving time.

The defense motion says Kline would be called a witness to testify and that the date of his testimony remains uncertain.

Kline is currently serving a 40-year prison sentence after pleading guilty to charges of child pornography.

Kline was behind the online profile that talked with Libby German in the days leading up to her death.

Meantime, the latest court filing in the case seeks to prevent prison guards from testifying. Prosecutors say Allen has confessed to the killings 61 times.

Allen has been in custody since Indiana State Police announced his arrest in October 2022. He has spent considerable time in “the hole,” or solitary confinement, which his attorneys argue has caused mental breakdowns and should render his confessions unusable in his defense.

Allen’s legal team also says that prison guards lack the necessary expertise to assess his condition and that their testimony violates a court rule regarding expert witnesses.

The trial begins with jury selection on Monday in Allen County. After being selected, jurors will be transported to Carroll County for the proceedings, expected to last three days.

According to multiple media reports, the month-long trial is projected to cost taxpayers several million dollars.
