DeWayne Craddock, a town engineer who was unleashed by a shooting in 2019, had been "obsessed for years" with critics at work, the F.B.I. mentioned.
A municipal engineer was obsessed for years with perceived workplace grievances before to kill 12 people lors of a 2019 shooting at a Virginia Beach municipal compound, the FBI said this week, releasing the results of a behavioral analysis that provided new insight into the motive for the attack.
The gunman, DeWayne Craddock, who was fatally injured by the police, had become alienated from his colleagues over how they viewed him and his own perception of his performance at work, according to the Office Behavior Analysis Unit findings .
"The shooter's exaggerated sense of self-importance contributed to this conflict and led him to believe that he was wrongly and repeatedly criticized and despised ", concluded the office. "Violence was seen by the shooter as a means of recoreconcile this conflict and restore his perverse view of justice. "
The findings, which were released on Wednesday, offer a measure of explanation for this which may be inexplicable to those investigating some of the nation's deadliest mass shootings: a shooter's state of mind. Several of these shootings remain a mystery, with investigators unable to determine a motive .
The ings office find contrasted with those of the Virginia Beach Police Department, which said in March that it might never know what made Mr. Craddock go crazy.
But the FBI, whose help was requested by local police, said Mr Craddock, 40, a former military, had become such a loner that it would have been difficult to imagine the bloodshed he would require.
"It s 'is intentionally isolated by disengaging from relationships to hide his intentions, "the office said, adding that " no individual or group was in a position to see the confluence of behaviors that may have prevented the 'attack. "
The city of Virginia Beach has been criticized by the families of the victims for its reluctance to say what prompted the gunman to open the tree May 31, 2019, in Building 2 of the Virginia Beach Civic Center.
On the morning of the shooting, Mr. Craddock, an employee of the town of about 15 years, had sent a resignation e-mail to his bosses.
"Despite an exhaustive investigation and despite rumors and unfounded accusations, it seems we never knowis why he did this heinous act, "the Virginia Beach Police Department said in a final investigative report that was released in March.
A city spokeswoman did not immediately respond to requests for comment Thursday, but told The Washington Post that the FBI 's analysis was not in conflict with the city ' s conclusions and was a continuation of the work started by the city.
" We asked the FBI to take a look at this because they had a level of expertise in this area that we did not have, "said Julie Hill, spokesperson. "This is part of the work we asked for. It was not forced on us.
The FBI saidthat he had informed the Virginia Beach Police Department of his findings, which noted that the gunman had suffered "significant mental health stressors" which appeared to have contributed in part to his prior decompensation. 'attack ".
" However, mental health stressors alone cannot explain the attack on Virginia Beach "the office said.
Investigators said the gunman was similar in many ways to others who carried out mass shootings and have been investigated by the FBI
"Mass shooting is a predatory act, usually planned and intentional violence against a target, 'a person, place or institution identified, "said the office.
