Teasia Montgomery, 28, was shot and killed on Rosewood Street in Boston’s Mattapan neighborhood in the early morning of January 27, 2014. Boston Police responded to reports of shots fired around 2:45 a.m. and found Montgomery gravely wounded on the sidewalk; a second victim, 25-year-old Clarence McGregor of Dorchester, was found in the street. Both were taken to area hospitals and later died. Montgomery was a mother and had completed a massage therapy certification at Lincoln Technical School; a family friend described her as a sweet woman working to improve her life.

Investigators and prosecutors treated the double killing as targeted and gang-related rather than random. Detectives and Suffolk County prosecutors spent two years examining ballistics, witness statements, and cell tower records and identified three suspects, each with prior gun-related convictions. Two men were arrested and arraigned in spring 2016, and a third suspect was taken into custody in May 2016.

Did anyone who knew Teasia or Clarence notice threats or tensions in Mattapan around that time?
