The state medical examiner on Thursday ruled that the death of a teenager who was found July 18 in a Mattapan rental property owned by Representative Ayanna Pressley’s husband was a homicide, police said.
Police also formally identified the victim as Yoseliani Ann Marte Ocasio, 18, of Boston.
No arrests have been made; police officials have said there’s “absolutely nothing that indicates any connection to the owners of the property” on Malta Street.
Pressley and her husband, Conan Harris, live in the Hyde Park section of Boston, according to her website.
“The Boston Police Department Homicide Unit is actively investigating the facts and circumstances surrounding this incident,” officials said in a statement Thursday.
Ocasio’s mother, Elenie Ocasio, previously told Boston 25 News that a perpetrator fatally shot her daughter in an act of domestic violence.
“He put a gun to her head, took my baby in that house, and left her to die,” she told the station.
She had identified her daughter at the time as Yoseliani Marte.
Pressley said in a recent statement that she is “devastated about the death of Yoseliani Marte, an 18-year-old with so many dreams ahead of her, her life cut short by domestic violence.”
Police have released no information about a suspect.
Pressley said that as a parent of a teenager herself, “the thought of a young person violently losing their life in this way is beyond crushing.”
The lawmaker said she stands with “our community and everyone who loved Yoseliani as we grieve this deep loss. May we all honor her life and humanity and extend compassion to her loved ones as they navigate this heartbreaking tragedy.”
Shea Butter Smoothies, a Dorchester juice bar where Marte worked, posted a heartfelt remembrance of her to Facebook on July 20.
“Liani was a brilliant and motivated young lady whose passion and dedication had a profound impact on our team and the work we do,” the business said. “Her innovative ideas, particularly in enhancing Shea Butter Smoothies, brought a unique touch that our customers adored. She approached every project with enthusiasm, creativity, and an unwavering commitment to excellence.”
She also “brought joy and positivity to our workplace. Her infectious laughter, kindness, and willingness to help others made her not just a colleague, but a cherished friend to many,” the post said. “She will be missed immensely, and her legacy will live on in the hearts of those who had the privilege of knowing her.”
To honor her life and support her relatives as they grieve, the business said, “we will be donating 50 percent of the proceeds from every purchase of the Big Papi smoothie to assist with her funeral costs. We encourage our community to join us in this effort, as we remember the beautiful person she was. ... Rest in peace, Yoseliani. You will always be remembered.”
