15-Year-Old Gracie Anne Muehlberger, 14-Year-Old Dominic Blackwell ID'd As Saugus High School Shooting Victims

SANTA CLARITA (CBSLA) — Two students fatally wounded when a 16-year-old opened fire at Saugus High School in Santa Clarita were identified Friday.

Gracie Anne Muehlberger, 15, and Dominic Blackwell, 14, were identified by the Los Angeles County Dept. of Medical Examiner-Coroner as the two students who died from gunshot wounds in Thursday's shooting.

The two teens were killed, and three of their classmates wounded, when Nathan Berhow opened fire on his sixteenth birthday at the high school.

According to investigators, surveillance video showed Berhow walk into the quad, pull a gun from his backpack, shoot five people around him, then turn the gun on himself – all within 16 seconds.

Responding Los Angeles County Sheriff's deputies arrived to find the six students, including Berhow, lying wounded in the campus quad.

Two more girls, ages 14 and 15, along with a 14-year-old boy, were hospitalized. The girls were both said to be in good and fair condition at Providence Holy Cross Medical Center in Mission Hills. A hospital spokesperson said they were "in good spirits," late Thursday afternoon.

Henry Mayo Hospital officials said one person who was brought to the hospital in good condition -- believed to be the 14-year-old boy -- was treated and released early Thursday afternoon.

Berhow succumbed to a self-inflicted gunshot wound Friday afternoon.

Multiple vigils appeared throughout Santa Clarita Friday night as neighbors helped one another navigate through their collective sorrow.

"So this has been a very traumatic situation for the community for my neighborhood in particular," said neighbor of the Blackwell family Dave Lyznick.

Lyznick lives right across the street from the Blackwell family who moved into the neighborhood about a year ago.

"They're an incredible family.   Very loving.  The kids are just full of life," he said.

Nadia Furmanski remembered her friend Gracie saying, "She loved to shop.  That was her favorite thing, and making outfits and taking pictures, and she was so funny."

Sheriff Alex Villanueva Friday provided updates into the investigation saying, "We know it was plan attack.  It was deliberate.  He knew how many rounds he had."

GoFundMe accounts were created for the families of Dominic and Gracie.
