The FBI has opened a domestic terrorism investigation into the Gilroy Garlic Festival shooting in Gilroy, California, which left three people dead and more than a dozen injured last month, officials announced Tuesday.
John Bennett, the FBI’s agent in charge in San Francisco, said the agency took over the case from the Gilroy Police Department to launch a “full, predicated FBI investigation” after discovering the potential existence of an ideological motive.
“We have not made a final investigative conclusion into the motive of the shooter. However, we have uncovered evidence ... that the shooter was exploring violent ideologies,” Bennett said Monday during a news conference.
Bennett said the shooter, 19-year-old Santino William Legan, had a “target list” that included “religious institutions, federal buildings, courthouses, political organizations from both major political parties, and the Gilroy Garlic Festival.”
“We have seen a fractured ideology,” he said. “The shooter appeared to have an interest in varying, competing violent ideologies.”
A spokeswoman for the FBI declined to provide additional details about the groups targeted by the shooter in an effort to “protect their privacy and safety.”
Officials say they believe Santino cut through a fence to gain access to the food festival on July 28 before opening fire on attendees, killing two children ― a 6-year-old boy and a 13-year-old girl ― as well as a man in his 20s.
The shooter, who wore a bullet-resistant vest, fired approximately 39 rounds into the crowd using an AK-47-style rifle during the attack, Gilroy Police Chief Scot Smithee said Tuesday.
The Santa Clara County medical examiner said Friday that the shooter died of a self-inflicted gunshot wound, contradicting initial police reports that officers fatally shot him soon after arriving on the scene.
The gunman was hit multiple times by police gunfire, though the medical examiner has not yet determined exactly where and how many rounds hit him, Smithee said.
Santino’s family said in a statement Tuesday that they are “deeply shocked and horrified” by his actions and denounced the “hateful thoughts and ideologies” that inspired the shooting.
“We want to express our deepest and sincerest apologies for the loss and pain that he has caused,” they wrote in the statement. “To the City of Gilroy and to everyone affected, we are tremendously sorry. No words can begin to express this.”
Santino did not leave behind a manifesto, officials said Monday. Investigators are working to determine a possible motive behind the shooting and have not ruled out white supremacy, Bennett said.
Days after the Gilroy shooting, a gunman opened fire at a Walmart in El Paso, Texas, killing 22 people and injuring two dozen others. Police arrested him and discovered a manifesto he had written that railed against a so-called “Hispanic invasion of Texas.” That shooting is also being investigated as a domestic terrorism case, officials said Sunday.
To the surprise of many Americans, there is no federal charge that broadly outlaws acts of domestic terrorism, though plenty of former counterterrorism officials and a group of FBI agents say there should be.
The lack of a federal terrorism statute applicable to non-Muslim shooters has typically made federal officials hesitant to call domestic terrorists what they are, even when the suspects are dead.
But amid a national debate over the disparate treatment of white supremacist terrorists and terrorists motivated by Islamic extremism ― as well as critiques of the FBI’s handling of the threat of domestic terrorism ― federal officials have recently become less cautious about labeling acts of domestic terrorism as such.
