BOSTON, August 28, 2018—A Dorchester man was held without bail at his arraignment today in the stabbing death of 77-year-old Marcelino Perez, Suffolk County District Attorney Daniel F. Conley said.

RAMON RODRIGUEZ-DELGADO, 41, was arraigned today in West Roxbury Municipal Court on a charge of murder in Perez’ fatal stabbing. At the request of Assistant District Attorney Amy Martin, Judge Mary Ann Driscoll ordered Rodriguez-Delgado held without bail.

Martin told the court that Rodriguez-Delgado lived in a building across the courtyard from the victim’s Shandon Street apartment building and had previously observed an individual arrive at Perez’ apartment in order to deliver prize money from a private lottery in which the victim was involved.

On the afternoon of July 26, a security camera captured the man leaving Perez’ building. Approximately eight minutes later Rodriguez-Delgado was captured on camera as he entered the building and then exited after several minutes. He returned to the building a short time later wearing different clothing and remained there for approximately 30 minutes. Prosecutors allege he stabbed Perez multiple times inside the victim’s apartment. Relatives discovered Perez’ body later that day.

Anite Cetoute is the DA’s assigned victim witness advocate. Rodriguez-Delgado was represented by Jim Coviello. He returns to court Sept. 13.
