The suspect, identified as Shamsud-Din Jabbar, exhibited "very intentional behavior" by driving his truck into crowds, indicating a premeditated desire to inflict harm
Shamsud-Din was a 42-year-old Army veteran, which raises questions about his mental state and motivations leading up to the attack
The FBI is investigating potential connections to extremist groups, particularly after discovering an ISIS flag in his vehicle and evidence.
Jabbar was reportedly experiencing significant personal issues, including financial difficulties and a recent divorce
Prior to the attack, he posted videos discussing his grievances, including thoughts about harming family members and expressing extremist views related to ISIS
Authorities found improvised explosive devices (IEDs) in his vehicle and nearby, indicating a broader intent to cause chaos beyond the vehicle attack itself
Investigators believe Jabbar may not have acted alone and are actively seeking information about any accomplices or associates who may have influenced or assisted him
The FBI has urged the public to come forward with any interactions they had with Jabbar in the days leading up to the attack, highlighting their belief that he had connections beyond his solitary actions
