A man charged with fatally stabbing a 77-year-old man last month in Boston's Dorchester neighborhood faced a judge Tuesday.
Rodriguez was ordered to be held without bail during his arraignment at West Roxbury District Court.
A surveillance image of a person of interest in the fatal stabbing was released by authorities last month; however, Rodriguez-Delgado is not the person depicted in the photo, according to Boston police.
The investigation into the stabbing is ongoing. Anyone with information is asked to call Boston police at 617-343-4470.
