SPRINGFIELD — A Holyoke man has pleaded guilty to murder in a 2019 killing in Springfield.

According to information posted by the Hampden district attorney’s office, Edwin Hernandez, 23, of Holyoke, pleaded guilty Monday to second-degree murder in Hampden Superior Court.

On June 11, 2019, according to the district attorney’s office, police responded to the intersection of Liberty Street and Genesee Street for a report of a gunshot victim, where they discovered a severely wounded Isaiah Ramos, 19, of Springfield, in the road.

Ramos later died of his injuries at Baystate Medical Center.

Hernandez was quickly identified as a suspect, according to the district attorney’s office, and was arrested the following day in Holyoke.

“The excellent investigation by Springfield Police Department’s Homicide Unit and my office’s Murder Unit led to a successful prosecution, directed by Assistant District Attorney Mary Sandstrom and appellate ADA Cynthia Payne,” said Hampden District Attorney Anthony D. Gulluni in a statement.

Per the plea agreement, Hernandez is expected to be sentenced Tuesday to life in prison with parole eligibility after 25 years.
