Alan P. Nadeau, who is accused of fatally stabbing his father's friend in Lebanon on April 12, has been found competent to stand trial for murder after spending two months at a state mental hospital.

Nadeau, 31, will be returned to prison to stand trial for the murder of Christian E. Beloin, 37, of Coventry, a friend of Nadeau's father who was sleeping on the couch at the Nadeau home on April 12.

According to police, Nadeau stabbed the sleeping Beloin in the neck with a bayonet, then turned himself in at Troop K, the state police barracks in Colchester.

His court-appointed attorney, Kevin C. Barrs, asked Judge Hillary B. Strackbein to order a competency evaluation for Nadeau following his arrest.

Clinicians from the state Department of Mental Health and Addiction Services reported in June that during the evaluation, Nadeau was unable to provide accurate information about himself and acted paranoid and delusional, according to testimony.

The judge committed Nadeau to the Whiting Forensic Division of Connecticut Valley Hospital in Middletown for treatment and restoration to competency.

Under the care of the state hospital, Nadeau "has been responding to his medication and is doing much better," according to Barrs.

After turning himself in to the state police, Nadeau had told investigators he had been prescribed antidepressants and anti-psychotic medications in the past but had not taken them for a year.

Barrs said his office wants a doctor to conduct an independent psychiatric evaluation of Nadeau before the case moves forward.

Barrs asked the judge to recommend to the Department of Correction that they house Nadeau at the Garner Correctional Institution, the state prison in Newtown that specializes in detention and treatment of mentally ill prisoners.

The judge agreed and continued the case to Sept. 24.
