Here's what we know about the 3 victims killed in Gilroy Garlic Festival shooting

(KABC) — A 6-year-old boy, a 13-year-old girl and a man in his 20s. Those are the three people who died when a gunman opened fire at the Gilroy Garlic Festival in California.

At least 25 people were sent to the hospital, according to representatives from four area hospitals. St. Louise Regional Hospital said one patient was among the dead. Of the injured patients, at least 12 were being treated for gunshot wounds, while the others had non-gunshot-related injuries.

Police said the gunman was also killed on Sunday. They identified the suspect as 19-year-old man Santino William Legan.

Here's what we know so far about the victims who were killed.

Stephen Romero

Stephen, who was just 6 years old, died in the shooting. He was with his mother and grandmother at the annual food festival. They were both hospitalized as well.

His other grandmother, Maribel Romero, said Stephen was "always kind, happy and, you know, playful."

San Jose City Councilwoman Maya Esparza said in a Facebook post Monday that the 6-year-old victim was her cousin. On Facebook she wrote, "Heartache and prayers for my cousins who were wounded yesterday and losing my little cousin, only 6 years old. And I'm angry, so angry. This violence has to stop. How do some people have such little regard for life.

Trevor Irby

A heartbroken grandmother, who lost her husband one month ago, is opening up about the death of her grandson in the shooting.

Over the phone from her Romulus home, Juanita Walborn talked about her beloved grandson, describing him as the "perfect child that any parent would want."

"He used to call me every night," she said. "He would tell me that he loved me. Then I'd tell him I loved him."

The 25-year-old graduated with a biology degree from Keuka College in 2017. In a statement, Keuka College President Amy Storey:

"It is with profound sadness that I share the devastating news that a member of the Keuka College family was among the victims of the mass shooting over the weekend in California.

The College community today mourns Trevor Irby, a biology major who graduated in 2017. Our hearts go out to Trevor's family and loved ones. We are shocked that this latest episode of senseless gun violence resulted in the loss of one of our recent graduates-graduates in whom we place so much hope because of their potential to create a brighter tomorrow.

We also send sincere condolences to College alumna Sarah Warner, who was with Trevor at the California garlic festival where the shooting took place. We were relieved to learn that Sarah was not physically injured in the shooting. We offer our support and prayers to Sarah and her family.

When the timing is appropriate, we will schedule a vigil on campus so that those alumni, students, faculty, staff, and community members who knew Trevor and who know Sarah can join in fellowship and reflection. In the meantime, anyone wishing to reach out for comfort or support is encouraged to contact College Chaplain Eric Detar at (315) 279-5378.

Again, the College community extends its deepest sympathies to Trevor's family, friends, and to all who knew him. And we offer condolences, support, and prayers to Sarah and her family."

Additionally, Romulus Central School District confirmed he was a 2012 graduate. In a statement they wrote:

"The school community of Romulus is deeply saddened to hear of Trevor's tragic death at the Gilroy Garlic Festival in California. All of our thoughts and prayers go out to Trevor's family & friends as well as the many families who are suffering from this horrible tragedy.

Trevor was a multi-sport athlete, member of the drama club, band and friend to everyone he knew here in Romulus. Although his path had taken him far from home, he was still close to many of his classmates and is missed by everyone. Trevor was the type of student who could bring joy, laughs, and comfort to everyone he met. We are proud of his accomplishments from Romulus, Keuka College, and his most recent endeavors during his time in California. On behalf of everyone at our school, our hearts go out to all the victims of this tragedy and we pray for peace and hope to come to all involved."
