Man Who Abandoned Woman's Body In Trash Bag To Be Arraigned: DA

BOSTON — A man is facing criminal charges after the District Attorney's Office says he disposed of a woman's body in a trash bag and then dumped it in a park in Boston last year.

Rinnyers Pena, 42, will be arraigned Thursday on a charge of disinterring a body, the Suffolk District Attorney's Office said.

The body of Alenny Matos, 38, was found in May 2020 in a trash bag in a swampy area of Stony Brook Reservation in Hyde Park after her family and friends reported her missing in January.

Prosecutors say Pena has already been held without bail since June of this year when he was arrested in connection to a different case involving a separate person on charges of kidnapping, rape, strangulation, assault and battery, and more.

Boston Police say they were first contacted by a relative of Matos on January 27, 2020, for a wellness check after multiple attempts to contact her proved unsuccessful.

A missing persons investigation was initiated and detectives gathered cell phone records indicating phone calls between Pena and Matos two days before her reported disappearance.

Security footage, cell phone site location and interviews suggest Pena picked Matos up from her Dorchester apartment on January 26, 2020, and drove her to his Norton Street residence. He later drove to Turtle Pond Parkway and Enneking Parkway inside the Stony Brook Reservation.

Prosecutors believe he transported Matos' body to that location and abandoned her there.

Months later, on May 9, 2020, a person walking around the Stony Brook area found Matos' remains inside a trash bag.

Prosecutors are awaiting the findings of the Office of the Chief Medical Examiner regarding the cause and manner of Ms. Matos' death.

"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 Rachael Rollins said. "This family deserves answers. Ms. Matos deserved better."
