An Indiana judge on Friday sentenced Richard Allen, who was recently convicted in the February 2017 killings of two teenage girls who were walking on a trail in Delphi. known as the Delphi murders, up to a maximum sentence of 130 years behind bars.

The sentence includes 65 years for the aggravated murder of Abigal “Abby” Williams and 65 years for the aggravated murder of Liberty “Libby” German, to be served consecutively.

Allen’s lawyers plan to appeal. A memo filed earlier this week said Allen “maintains his innocence and hopes the appeal process will give him the opportunity to present a full defense at a second trial.”

An Allen County jury found Allen guilty in November of murdering 13-year-old Abby and 14-year-old Libby, who disappeared while walking along the High Monon Trail on Feb. 13, 2017. Investigators determined that both were brutally murdered the next day with sticks covering their bodies in a wooded area near the trail.

Allen’s defense relied largely on expert analysis showing Allen’s unhealthy mental state following his arrest in 2022, which surprised the Delphi community at the time. Allen was a longtime CVS employee in the small Indiana town when police took him into custody five years after the murders.

Carroll County Prosecutor Nick McLeland told jurors in his opening statement that Libby was naked and covered in blood when searchers found the two girls in a wooded area near the Monon High Bridge. Both girls had their throats slit several times FOX 59 reported.

Prosecutors argued that Allen was “Bridge Guy” after witnesses who testified against Allen said they saw him on the trail around the same time the girls disappeared, and authorities found a similar blue utility jacket in 2022 Allen’s house had been secured.
