BOSTON — A Boston man is expected to be arraigned in court Thursday after he was accused abandoning a woman’s body inside a trash bag at Stony Brook Reservation last year.
Rinnyers Pena, 42, will be arraigned in West Roxbury Division of Boston Municipal Court on charges of disinterring a body.

Pena has been held without bail since his arrest in June in connection with a separate case charging him with kidnapping, rape, strangulation or suffocation, assault and battery on a household or family member, photographing an unsuspecting person in the nude and distribution of a Class A substance.
Investigators said those charges reflect offenses committed against a second, different victim and are not related to the ongoing death investigation of Alenny Matos.
A relative of Matos called Boston police on January 27, 2020 to request a wellbeing check after trying to contact her for two days without success.

Police could not find Matos and a missing person investigation began.
During the investigation, police said they obtained cell phone records of calls between Pena and Matos on January 25, 2020. Evidence gathered, including cell site location information, security camera footage and interviews, suggested Pena picked Matos up at her Dorchester apartment on January 26 and drove her to his Norton Street home.
Police said he later drove to the area of Turtle Pond Parkway and Enneking Parkway inside Stony Brook Reservation.
He then allegedly took Matos’ body to that location and left her there.

Someone walking in the area located Matos’ remains inside the trash bag on May 9, 2020.
The cause and manner of Matos’ death is still under investigation by the Office of the Chief Medical Examiner.
“Everyone deserves to be treated with care and dignity. The evidence gathered during the course of our investigation suggests that Mr. Pena chose to treat Ms. Matos with anything but care and dignity when he disposed of her body inside a trash bag following her death,” District Attorney Racheal Rollins said. “As we continue to investigate Ms. Matos’ death, we ask that anyone with information that could aid in this or other investigations share what they know with the police or prosecutors in my office. This family deserves answers. Ms. Matos deserved better.
Anyone with information on the investigation can call the Boston Police Department tip line at 1-800-494-TIPS or the Suffolk County State Police Detective Unit at 617-727-8817.
