The trial for John Odgren has been delayed while prosecutors appeal to the Supreme Judicial Court of Massachusetts over the tapes of Odgren’s prison phone conversations.
Odgren is accused in the 2007 stabbing and slashing death of fellow Lincoln-Sudbury Regional High student James Alenson.
Odgren’s lawyer is trying to use Odgren’s alleged Aspergers as a diminished capacity defense.
The prosecution states that the tapes will show that Odgren does not communicate like an Asperger’s patient.
The prison tapes were previously ruled inadmissible.
No new date has been set for the trial.
