Brown's mother, Yvonne Paige, said he was a good son and thoughtful man who was protective of his children and always helped his friends.
"I keep thinking he is coming home and he will be home. He was very thoughtful. I am going to miss him," she said.
Alex Guerrero, 27, who was an assistant manager at the Jack In The Box until eight months ago, said there are no security video cameras at the restaurant.
"We would always tell the owner to get cameras, but he always said he can't afford them," he said.
By Monday morning, relatives of the victims were arriving at the restaurant parking lot. One woman slumped over the trunk of a car, overcome with grief.
Sunday night's crime is the first multiple homicide of workers in the San Diego-based company's 51-year history, Jack In The Box corporation officials said Monday.
Restaurant owner Adel Farag is offering a $10,000 reward for the arrest or indictment of those responsible.
The neighborhood near the restaurant is a mix of palm tree-lined mobile home parks, restaurants frequented by senior adults, and paint, tire and auto parts stores. Just down the street are rows of RV dealerships and $139-per-week motels.
Many people in the area are of retirement age, including some who use their golf carts to get from their mobile-home parks to eat or shop. Some often came for breakfast at Jack In The Box.
But some who work and live nearby see a neighborhood that has changed for the worse in recent years.
They say an auto shop and convenience store in the area were recently robbed, and employees at Flynn's Carpet-Tile recounted numerous robberies in recent years.
"The neighborhood is nasty," said Robert Timberman, Flynn's warehouse manager. The business added cameras and an alarm system, though the troubles continue.
"The whole neighborhood is going down the hill. It has really decreased in the past three years," said Laura Bohorquez, 31, who used to live in the area and was there Monday with a friend. Not everyone agrees.
Mark Horvatich, an assistant manager at a nearby Sherwin-Williams paint store, said that while other stores near his have been robbed, "we've never had any problem whatsoever. It's a neighborhood I've never felt unsafe in."
The homicides shook the restaurant community.
Merrilyn Halverson, vice president of member services for the Arizona Restaurant Association, said the shootings "just made me sick. As part of the hospitality family, something like this hits us doubly hard."
Goulet urged anyone with information to call police at (480) 644-2211 or Silent Witness at (480) WITNESS.
