2006 Quincy Murder Conviction Upheld

QUINCY, MA — The state's highest court has ruled against a Mattapan man convicted in a 2006 murder that took place in Quincy.

The state's Supreme Judicial Court rejected an appeal from Deryck Long, who will remain in prison with no chance of parole. The 24-page decision from the court rejects both Long's appeal and his motion for new trial, according to the Norfolk District Attorney 's office.

“We are gratified that the SJC has affirmed the first-degree murder conviction and rejected Long’s claims that mistakes by his attorney and a motions judge should disturb the verdict,” District Attorney Michael Morrissey said in a statement. “Although the murder precedes my tenure as District Attorney, my review of the evidence shows very clearly that Long drove to Willard Street in Quincy that night armed and with the intention of murdering Mr. Vaughn. I am pleased for Mr. Vaughn’s family and friends that the SJC has put this to rest.”

Long was convicted of the murder in 2011 and sentenced to live in prison without parol. Hours before the murder, Long and Jamal Vaughn had been in a brief altercation while Long was retrieving belongings from an apartment where he had frequently stayed with a former girlfriend. Long was murdered outside a Quincy apartment.
