NORTHAMPTON — A former Holyoke man who pleaded guilty to second-degree murder in Northampton three decades ago has been released on parole, according to the Massachusetts Parole Board.

Tony Quinones was serving a life sentence when he appeared before the review board in February. The board announced July 11 its decision to parole Quinones, which is the name used throughout its report. The board noted that he now uses the name Anthony Q. Core (his mother’s last name).

Quinones, now 60, also pleaded guilty to assault with intent to murder in 1984. Quinones was at his mother’s Northampton apartment the evening of Sept. 21, 1984, when he got into an argument with William Diaz after Diaz allegedly hit Quinones’ sister and mother, according to the board’s report.

Quinones noticed Diaz was outside the apartment and while carrying a gun approached him and the other man. Diaz and the other man ran toward the back of the apartment, and Quinones fired in their direction, delivering a fatal gunshot to the back of Diaz’s head, according to the board.

Quinones previously was paroled May 12, 2004, but was returned to custody in April 2013 after he was charged with filing a motor vehicle insurance claim, attempting to commit a crime and making a false report, according to the board. He was convicted of the charges in June 2014 and sentenced to 2 ½ years in the House of Correction that was to be served concurrently with his previous life sentence.

When he returned to custody, Quinones occupied his time working with intensive treatment patients at Bridgewater State Hospital, according to the parole board.

Board members noted in their report that Quinones “has maintained a positive record within the correctional institution since being returned to prison … (and) appears empathetic and is insightful of his actions that resulted in the death” of Diaz.

The board voted unanimously to grant parole for Quinones with conditions that include no contact with the victim’s family, no drug or alcohol use and attendance at least once a week at Alcoholics Anonymous meetings.
