The exact content of the letter has not been made public, but was sent to the mayor’s office in April, according to CNN.
However, the Boston Herald reported the letter blasted Abraira as a “ghost fire chief” who “never announced his arrival on the radio or assumed any command authority” at the April 15 bombings.
According to the Herald, the letter also stated, “At a time when the City of Boston needed every first responder to take decisive action, Chief Abraira failed to get involved in operational decision-making or show any leadership.”
There was no response Tuesday from the Boston Mayor’s office.
The twin bombings killed 3 and left another 260 wounded.
