Young Austin Kamp’s path to a career was clear and bright.

“He was studying to become a real estate agent,” said his mother, Carina Lujambio. “We were going to start our own real estate company.”

She said that won’t happen now that he was among the six mass murder victims that included his older brother and his father.

 “We were hoping to incorporate all the boys,” in the real estate company, Lujambio said of her four sons. “We’ve never been apart for more than a few days.”

She added: “My four sons and I are way more than mom and sons. They’re the reason I was born.”

Despite their parents’ divorce and a 2012 move back to California, where he had once lived, Austin remained close to relatives in Texas, where he attended Plano West High School in suburban Dallas.

But his mother said there were some things that did not change: like family dinners at the Oceanside, Calif., house the two oldest brothers – Austin and Nathan —  shared.

They were there the night before Kamp and his brother left for Texas to spend time camping and hunting with their dad. 

Unlike his brother, Austin was too shy to let his mom take a video of him as the kids danced at the Oceanside home the night before departing. 

Lujambio’s voice breaks when she talks about her murdered sons, the careers ahead of them, the love of family and opportunities they had to change the world for the better.

“They were just so loving; so cute,” she said.

 “Oh my gosh. I’m not dealing with it. I don’t know if there is a recovery for this. These are people I can’t live without.”
