Ronaldo Cepeda, a 16-year-old Dorchester youth, was held without bail on a murder charge for the fatal stabbing at Jackson Square T Station on Oct. 22, according to a press release from the Suffolk County District Attorney’s Office.
Assistant District Attorney Amy Galatis told Judge Paul McManus that Cepeda got off a bus and sat down on a bench outside the station’s turnstiles at around 3:20 p.m. A short time later, Raymond entered through a nearby door.
The two, who knew each other, spoke briefly but the words escalated into a physical fight, according to McManus.
Boston Police Department (BPD) and MBTA Transit police officers responded to a radio call for a person stabbed near the Jackson Square MBTA station at about that time, according to bpdnews.com.
Upon arrival, the officers observed Mason Raymond suffering from what appeared to be stab wounds. Raymond, 17, was transported to Brigham and Women’s Hospital, where he was pronounced dead at 4:30 a.m. due to a single stab wound to the chest.
At about 2:00 am on Friday, BPD and Transit officers identified and arrested the suspect, Ronaldo Cepeda, in his home, where he was given his Miranda rights and interviewed in the presence of an adult family member. He allegedly made incriminating statements in the course of that interview.
Cepeda was arraigned in Roxbury Municipal Court for the incident. Although he is a juvenile, Massachusetts law mandates that all murder defendants aged 14 or older are charged as adults.
Cepeda is represented by attorney Veronica White, who did not respond to a request for comment. Cepeda will return to court on Nov. 16.
