A 35-year-old Dorchester woman wearing an electronic ankle monitor is facing charges after Boston police say she stabbed a man at 950 Blue Hill Avenue, then was identified by detectives as one of the reporting parties in another district case, with what appeared to be red stains on her sneakers. Jasmine Noiles was arrested and charged with assault and battery causing serious bodily injury and assault and battery with a dangerous weapon on a person over 60, according to police.
Boston police responded to a report Thursday, September 10, 2026, at about 8:46 p.m. that a person had been stabbed at 950 Blue Hill Avenue, according to a statement cited by MassLive. Officers responding to the address found a man suffering from lacerations to the neck and head; he was treated at the scene and taken to a local hospital, where his injuries were determined not to be life-threatening. The Sportsmen's Tennis & Enrichment Center is a nonprofit founded in 1961 as the nation's first African-American-built indoor tennis facility, according to the Sportsmen's Tennis & Enrichment Center.
GPS Data and a Chance Encounter at the Station
According to the Boston Police Department, GPS tracking data from the Electronic Monitoring Office, known as ELMO, allowed investigators to analyze location activity in real time and confirm Noiles's presence in the immediate vicinity at the time of the stabbing. Police had described the suspect as a woman with short hair, a black hoodie, black shorts, and an electronic ankle monitor, per the same account.
The break in the case came under unusual circumstances: Noiles was identified as one of the reporting parties in another district case, and detectives recognized her as matching the stabbing suspect's description and spotted what appeared to be red blood stains on her sneakers, Patch reports. District B-3 detectives had been assigned the case involving Noiles, and investigators noted she was wearing an ankle monitor and had what appeared to be red stains on her shoes, according to police. District B-3, headquartered at 1165 Blue Hill Avenue, covers the Mattapan and North Dorchester neighborhoods, per the department.
Charges and What Comes Next in Court
Noiles is scheduled for formal arraignment on assault charges in Dorchester District Court, according to Patch's report. Patch's report lists assault and battery with a dangerous weapon on a person over 60 among the charges.
Court records show Noiles was previously arrested in February 2017 by Somerville police on charges of larceny over $250 and unlawful removal of a theft-prevention device at a store in Assembly Row, according to the Somerville Times. It remains unclear why Noiles was placed on electronic monitoring or what led to the alleged assault.
How Electronic Monitoring Factored In
The Massachusetts Electronic Monitoring Program is referenced in information about electronic ankle monitors, according to Mass.gov.
In this case, that same monitoring infrastructure gave investigators a fast way to identify Noiles's presence in the immediate vicinity as officers arrived. It's a detail that underscores how thoroughly location data now shapes fast-moving police investigations in Boston, even as questions remain about the circumstances that put Noiles under supervision in the first place.
