Hayes, who has a history of suicide attempts, also sent a suicide note to The Hartford Courant in which he called Northern a “psychological torture chamber,” the newspaper reported.
The Courant, citing a state official familiar with the incident, reported Hayes had saved up prescribed medication, including antidepressants, and took it all at once.
Hayes, 50, is on death row for the 2007 killings of a woman and her two daughters after a night of torment inside their home in Cheshire. Another man, Joshua Komisarjevsky, also was convicted and sentenced to death for the home invasion killings.
A federal judge in November denied Hayes’ lawsuit seeking to change his conditions at Northern Correctional Institution, ruling that he did not provide any evidence that his mental health treatment was inadequate or to back up his request for changes to his diet.
Hayes also said his legal papers were confiscated as a form of harassment or retaliation. The judge said the failure of prison staff to provide a full response to that claim “gives the court pause,” but he said Hayes had not shown irreparable harm.
Hayes more recently filed an emergency motion seeking relief, saying his prison cell was too cold and that he was misdiagnosed by staff who claimed his suicidal tendencies, depression and other issues stemmed from his crime rather than his conditions.
“I would rather die than endure these conditions any longer,” Hayes wrote last month.
Hayes did acknowledge that he should be in prison.
“I do not deserve to be psychologically tormented or refused proper treatment,” Hayes wrote. “To date I still suffer from deep emotional periods when I reflect on the pain I caused due to my crime and past actions.”
In court papers, prison staff members deny harassing Hayes or violating his rights. Hayes was subject to discipline after he violated rules by sitting on the floor in protest of a search of his cell and refusing to return his handcuffs upon returning to his cell, officials said.
A Department of Correction spokesman declined to comment.
The attorney general’s office, representing prison staff, said Hayes’ cell is kept at 74 degrees, not 55 degrees as he claimed, and that mental health treatment was available to Hayes but he refused it.
The Courant reported in 2012 that Hayes, who is deathly allergic to oysters, had concocted an elaborate suicide plan while on death row. He had promised to give information about unsolved killings that he lied about committing in exchange for being served oysters, hoping to die from an allergic reaction.
