Friday Night Special: Shocking New Delphi Killer Conversations Revealed

The jury took two minutes from entering the courtroom to announce the verdict: Richard Allen, guilty on all charges.

Allen was convicted of felony murder for Abby Williams and Libby German, as well as for knowingly and intentionally killing both girls. Judge Gull maintained order in the courtroom, where there were no outbursts, but outside on the streets of Delphi, shouts of "Guilty on all charges" echoed.

The jury, composed of seven women and five men, heard 17 days of testimony, including dozens of witnesses, disturbing jailhouse videos of Richard Allen, and photos of Abby and Libby as they were found at the crime scene.

They deliberated for 19 hours over parts of four days to reach a unanimous verdict. Richard Allen was found guilty of four counts: two counts of felony murder and two counts of knowingly and intentionally killing Abby Williams and Libby German.

Delphi residents tell reporters that they are still in shock after learning that local pharmacy tech Richard Allen has been charged in the 2017 murder of teens Liberty German and Abigail Williams.

Photos of Allen in a local bar with the police sketch of the murder suspect posted on the wall behind him have surfaced.

We have also learned that while at work, Allen developed photos of the girls, to be used at their funeral, for the families at no charge.

Police say Allen came forward as a witness in the early days of the investigation, but nothing at that time linked him to the crime. Now a new book details admissions Allen made to his mother.
