BOSTON — A 27-year-old man with ties to Randolph, Massachusetts, was ordered held without bail at his arraignment Tuesday in court on charges he killed one person and shot four others early Monday morning at a Hyde Park Haitian restaurant.

Oliver Derima was arraigned in BMC’s West Roxbury District Court, where he hid from the cameras, and a not guilty plea was entered on murder and other charges stemming from the shooting death of a 26-year-old man in Hyde Park early Monday morning.

DA Kevin Hayden ripped the “disregard for the sanctity of life” in a statement prior to the arraignment as this latest shooting hits on the two-day National Night Out anti-violence push.

“Heinous acts like what happened a few days ago in Hyde Park show an utter disregard for the sanctity of life and tear at the fabric of our communities. I thank Boston police homicide detectives and my office’s homicide unit for such quick and effective work leading to this arrest of the man directly responsible for the killing. This investigation is continuing and we will hold anyone involved in this multiple shooting accountable for their actions,” Hayden said.

The suspect’s lawyer, Anthony Ellison, said on the courthouse steps that his client was not the shooter and was actually shot himself during an altercation at the eatery just after midnight on Monday.

Derima’s past court records are peppered with entries for various charges from non-payment of rent to cocaine trafficking, where that charge was nolle prossed — dropped by a prosecutor with notice the state could refile charges.

Update: Murder victim identified

Boston police announced one of the five victims shot in the restaurant melee who later died is Ky Mani Korey Reynolds, 26, of Dorchester. He was pronounced dead at the hospital.

Derima, of Randolph, is charged with murder and unlawful possession of a firearm and ammunition. He is due back in court for a probable cause hearing on Sept. 4.

The Boston Police Department’s Homicide Unit continues to actively review the facts and circumstances surrounding this incident. Anyone with information is strongly urged to contact the Boston Police Homicide Unit at 617-343-4470.
