GILROY, Calif. (KTVU) - Authorities on Thursday announced the names of the three Gilroy police officers who confronted and killed the gunman in Sunday's mass shooting.
Gilroy Police Chief Scot Smithee said the officers are all veterans of law enforcement adding that they believe they were just doing their job.
Officer Eric Cryar, a 23-year veteran, Officer Hugo Del Moral, a 17-year veteran and Officer Robert Basuino, a 13-year veteran with the force, all took down shooter, 19-year-old Santino William Legan.
Smithee said his officers responded in less than a minute, and Legan turned his "AK-47-type" gun on them. The officers returned fire, killing Legan, who legally purchased the weapon in Nevada, according to a report from the Associated Press.
"I can't tell you how proud I am of the officers who were able to engage this guy as quickly as they did," the police chief said. "We had thousands of people there. It could have gone so much worse so fast. ... There absolutely would have been more bloodshed."
Investigators say Legan, dressed in camouflage, entered the fairgrounds by cutting a perimeter in a fence before firing into the crowd, killing 6-year-old Stephen Romero of San Jose, Keyla Salazar, 13, also of San Jose, and 25-year-old Trevor Irby from New York.
Smithee said an additional victim came forward who had sustained a graze wound, bringing the total of people injured to 16.
John Bennett with the San Francisco FBI division insists that investigators have not uncovered a motive for the attack, nor have they determined if Legan was aligned with a specific ideology.
Bennett says a behavioral analysis unit was called in to take a holistic look at what may have driven Legan to carry out the attack.
Response teams from across the country are also assisting with the investigation. There's a team of technical specialists combing digital media for any clues.
Bennett says detectives have processed 50 percent of the crime scene but says it will take some time to get through the rest.
Smithee said to his knowledge Legan's family has been cooperative with the investigation, but he does not know to what extent.
