An overnight crime scene investigation shut down a key stretch of Blue Hill Avenue at Mattapan Square early Saturday, snarling traffic through one of the neighborhood's busiest commercial hubs while Boston police combed for evidence.
According to WCVB, Boston Emergency Medical Services said three people were taken to nearby hospitals after a serious incident overnight, and Boston police established a crime scene on Blue Hill Avenue around 1 a.m. The station reported that investigators placed evidence markers in more than a dozen spots across the roadway and said it had reached out to police for additional details.
Investigators Work a Wide Scene
Video from the square showed officers moving through a taped-off area while what appeared to be forensic teams documented items on the pavement. The Boston Police Department's guidance for serious investigations details how officers are expected to secure perimeters, protect potential evidence and prepare materials for laboratory analysis, as outlined by Boston Police.
Another Violent Episode on Blue Hill Avenue
Saturday's investigation comes on the heels of another deadly incident on the same corridor earlier this month. On June 20, a woman was killed after being struck during an alleged carjacking on Blue Hill Avenue, as reported by Boston Globe. That crash led to extended closures between Woodhaven Drive and Mattapan Square while detectives conducted their work.
What Neighbors Can Expect Next
As of Saturday morning, Boston police had not released further information on any arrests or a possible motive, according to WCVB, which reported that it had requested comment from the department. Residents, business owners and commuters in the Mattapan Square area should be prepared for ongoing police activity and traffic delays while detectives continue processing the scene and tracking down leads.
