"Growing up with a dad that would literally wear his shoes until the soles of the shoes would separate just to make sure we had food on the table," said Joe Vegas, Gus' son Friday afternoon.
The Vegas' are a family whose love knows no limits.
"The compassion, the generosity and the love we are receiving was a testament to the life that he led," said Joe Vegas.
His life was marked by service. "A life as a police officer that he devoted to protecting others and a life as a father, that he ultimately sacrificed while protecting his family," Joe Vegas said.
Officer Vegas' life ended early Thursday morning. The father of one of his grandchildren, 30-year-old Robert Vega, is accused of shooting and killing him. Sandra Vegas said Vega called Gus "Dad."
In a moment of gripping fear, Sandra says she jumped from the home's second story window. She said she didn't think she'd see her 6-year-old grandson again. Officers apprehended Vega who had the little boy without incident at his Fairfield apartment.

Any loss is tragic, especially a fallen officer. This loss is equally confusing. And while answers are hard to come by, the faith that guided the Vegas family to open to their hearts to love is the same faith that's keeping their hearts open now.
"Through God and family and friends we will get through this and I know it brings peace to my dad to know that we won't do it alone," Jope vegas said.
Sandra Vegas said her husband was her protector and she was the one who got to hear his stories every night.
