The victim's husband, Miguel, found his wife bleeding and unresponsive when he came home from work on Monday afternoon. He called 911, but when paramedics arrived to the home on the 9200 block of Juniper Avenue, she was unresponsive with traumatic injuries. She was declared dead at the scene.
Police said the mother had obvious signs of blunt-force trauma to her upper body.
"We know them. They are good persons, good father, good mother," said the victim's friend, Oliver Ramirez. "They love Jesus, they (go) to church. I don't know what happened," he said.
Fontana Police Sgt. Jeff Decker said they have interviewed the husband extensively.
"He's been cooperative with us," Decker said.
Neighbors said Gonzalez would always walk her two young children to and from school, but on Monday she did not pick them up in the afternoon. Authorities said the children were not at home at the time of the attack.
"Real nice lady, you wouldn't think somebody would do anything to her like this," said neighbor Alfredo Viayra.
Friends said Gonzalez was a member of a San Bernardino church and would open her home for Bible studies. They said she was a woman who loved God and her family.
Neighbors said the family had been burglarized in the past. Police have not said if they believe the family had been targeted, or if Gonzalez was the victim of random violence.
The exact cause of death has not yet been determined. An autopsy has not yet been performed.
No one has been arrested. Investigators said they really need the public's help in the case. Anyone with information is urged to call Fontana Police at (909) 350-7700.
