In the summer of 2026, the life of 18-year-old Yoseliani Marte, known affectionately to her friends and family as "Liani" or "Mookie," was tragically cut short. On the afternoon of Saturday, July 18th, Boston police responded to a call and discovered Yoseliani's body inside a residence on Malta Street in the Mattapan neighborhood. She had sustained a single gunshot wound and was pronounced dead at the scene.
The Office of the Chief Medical Examiner would later officially rule her death a homicide, confirming the fears of her loved ones. The property where Yoseliani was found was a rental home owned by Conan Harris, the husband of U.S. Representative Ayanna Pressley. However, law enforcement officials have stated there is no evidence to suggest any connection between the property owners and the tragic event.
Yoseliani was remembered as a vibrant and kind-hearted young woman with a bright future ahead of her. Her family, including her mother Elenie Ocasio and father Jose Marte, described her as a beautiful soul whose smile could light up any room. She worked at Shea Butter Smoothies, where she had a favorite smoothie called the "Big Papi," and was known for her infectious laugh and caring nature. In the days following her death, a memorial of candles and balloons grew on the sidewalk outside the Malta Street home, a testament to the many lives she had touched in her short time. Her family, grappling with an unimaginable loss, expressed their profound grief and gratitude for the community's support.
The investigation into Yoseliani's death is ongoing, led by the Boston Police Department's Homicide Unit. As of early August 2026, no arrests had been made, and police had not publicly identified any suspects or a possible motive. Yoseliani's mother, Elenie Ocasio, has been vocal in her belief that her daughter was murdered, stating to the media, "This coward killed my baby. He put a gun to her head, took my baby in that house and left her to die." Both Ocasio and Representative Pressley have made statements that suggest the death may have been related to domestic violence. The case remains an active homicide investigation, with authorities appealing to the public for any information that could lead to an arrest and bring justice for Yoseliani and her grieving family.
