He officially appealed his murder convictions this past December, one year after he was sentenced to 130 years behind bars. He was found guilty of the murders of 13-year-old Abigail Williams and 14-year-old Liberty German, whose bodies were found near the Monon High Bridge Trail in Delphi on Valentine's Day, 2017.  

His appellate attorneys argue that the original document that led to the search of Allen's home and his eventual arrest contained mischaracterizations of witness statements. 

They also argue his 13 months in solitary confinement ahead of trial were "psychological coercion," and therefore deem his prison confessions unreliable. They argue those confessions should never have been admitted at trial.  

And finally, they argued his rights were violated because he was unable to present a complete defense. One of the initial police sketches after the murders, which they say looks nothing like Allen, was prohibited from trial. Allen was also unable to offer his alternate theory of events that Odinists actually committed the murders as a ritualistic killing.  

The state, in its response filed by the Indiana Attorney General's office, refutes all these claims and maintains the trial was proper. It asks the Indiana Court of Appeals to uphold the jury's verdict and Allen's murder conviction.  

The Indiana Court of Appeals will now decide whether it will hear oral arguments before deciding on Allen's appeal.  

In the Motion for Oral Argument, Allen's counsel lists the following in support of scheduling oral arguments:

"1. This case is factually complex spanning 22 volumes of transcript, 15 volumes of electronic exhibits, and multiple volumes of conventional exhibits. An oral argument will put facts in context and answer any questions.

2. This also involves an issue of first impression – Whether Allen’s statements made during a psychosis caused by his prolonged maximum security solitary confinement were voluntary and

admissible.

3. This case also involves the important constitutional issue of the right to present a defense."
