BOSTON (WBZ NewsRadio) – District Attorney Rachel Rollins said “this is a sad day” after more details have come out following yesterday’s mass casualty in Winthrop.
The suspect has been identified as 28-year-old Nathan Allen.
Allen reportedly shot and killed two people before stealing and crashing a truck into a building on Veterans Road in Winthrop. The incident occurred around 2:45 p.m. on Saturday.

Today police uncovered what is being labelled as “white supremacist rhetoric” in Allen’s own handwriting.
Rollins said that this writing featured “anti-Semitic and racist comments against black individuals.” It is not clear where this writing was found. Rollins also said that both victims were "visible people of color."
One of the victims of Allen’s crimes was identified as retired MSP Trooper David L. Green.
Green, who was murdered outside his house on Beach Road, served 36 years in law enforcement. He retired on Dec. 31 of 2016.
At the moment Rollins says this is being investigated as a possible hate crime.
Although Allen will no longer be a threat to others as he was shot and killed by police Saturday, the DA says “these families deserve answers and we will find out what happened here.”
