"I don't want to get into specifics of it, but things that have occurred around the time of his arrest made it clear to us that it was appropriate that we should inquire," said Richard Meehan, Plaskon's defense attorney.
"I think every case is different and we'll just have to wait and see how long it takes the doctors to complete their work to review and how long it will take us to prepare for a trial," said Kevin Lawlor, state's attorney.
On Tuesday, Eyewitness News learned that Plaskon has been very vocal while behind bars. He's been writing letters to his family regarding the murder, and talking with them during visits at the Cheshire Department of Corrections.
The transcripts are still sealed because officials are worried that details would compromise the case, however at least in one instance, Plaskon wrote the "voices" in his head were the reason behind the murder.
Court documents shed light on Plaskon's troubled thoughts. His parents said he struggled for years with mental health issues and knew he was struggling with depression after Sanchez's prom rejection. They insisted to police that they had no idea he was capable of murder.
Documents also touched on heroic efforts from that tragic day. Teacher Marie Reshenk tried to get Plaskon off Sanchez, while teacher Richard Rosen saw Plaskon allegedly throw the knife away.
It is unclear if this will go to trial. Lawyers will meet next year to discuss a possible plea deal, and several doctors have examined Plaskon's mental health and their diagnosis could be a key factor in if this goes to trial.
If convicted, Plaskon could face anywhere from 25 to 60 years in prison.
