The suspect in a triple stabbing that left Daniel Hernandez-Martinez dead in an early morning street fight was held without bail at his arraignment on murder and related charges, Suffolk County District Attorney Daniel F. Conley said.

OSCAR GUTTIEREZ-NUNES (D.O.B. 2/11/84) of Chelsea is charged with murder for allegedly stabbing Hernandez-Martinez to death near the intersection of Everett Avenue and Carter Street just before 1:00 Friday morning. He is additionally charged with two counts of armed assault with intent to murder for allegedly stabbing a 29-year-old East Boston man and a 19-year-old Revere man during the same incident.

At the request of Assistant District Attorney Holly Broadbent, Chelsea District Court Judge Benjamin Barnes ordered Guttierez-Nunes held without bail and ordered him to return to court on April 7.

Broadbent told the court that the incident began as an altercation inside the Acapulco Lounge on Everett Avenue. Members of the bar staff escorted Guttierez-Nunes and another man out of the establishment, Broadbent said, and the victim’s group left voluntarily a short time later.

Outside the bar, the two groups became embroiled in another conflict, prosecutors say. It was during that conflict that Guttierez-Nunes allegedly stabbed Hernandez-Martinez, inflicting fatal injuries. The victim tried to escape but collapsed on the street nearby. He was later pronounced dead at Whidden Memorial Hospital.

Guttierez-Nunes allegedly stabbed the other two men, as well. One got into his car a short distance away, where he lost consciousness and was found by first responders. He was admitted to Massachusetts General Hospital in critical condition, but his condition has been upgraded to stable. Investigators believe he struck Guttierez-Nunes with his vehicle before losing consciousness.

The second man was injured less seriously and later admitted himself to MGH; he has been released from the hospital.

Broadbent said Guttierez-Nunes returned to his Orange Street home, removed and discarded his clothes, and admitted himself to Whidden Memorial Hospital under the name “Elvin Guttierez.” Guttierez-Nunes was seeking treatment for injuries sustained, he said, when an unknown vehicle hit him and left the scene.

A search warrant executed at his home led to the recovery of clothes consistent with a description of the assailant, which were saturated with what appeared to be blood.

Catherine Rodriguez is the DA’s assigned victim-witness advocate. Guttierez-Nunes is represented by attorney Scott Curtis.
