SAN DIEGO _ The 9-year-old boy who survived a murder-suicide in the Paradise Hills community that left his parents and three brothers dead is fighting for his life, family members said.
The child's father is suspected of shooting his children and their mother in the boy's home Saturday morning, police said.
Officers found the parents and a 3-year-old boy dead at the scene. The other brothers were rushed to hospitals where two of them died.
The parents were estranged, according to investigators, and the mother had just obtained a temporary restraining order against the father the day before.
Late Saturday night, the woman's brother, Karl Albright, created a GoFundMe to help raise money for medical expenses and funeral costs. He said 9-year-old Ezequiel remained in an intensive care unit on life support.
Family and friends identified the slain mother as 29-year-old Sabrina Rosario. Albright identified her other sons as 11-year-old Zeth, 5-year-old Zuriel and 3-year-old Enzi.
"Anything is a welcome blessing to help us through this tragic moment in our lives," the brother said.
Police said they are still investigating the slain couple's history. Police had gone to the house at least one before, two weeks ago, when the man came over to retrieve tools.
During that Nov. 1 incident, officers were there to "preserve the peace," police said.
Investigators have not confirmed the identities of anyone involved in the domestic-violence incident.
