A San Diego man murdered his wife and three of their four sons less than 24 hours after she obtained a restraining order against him, police say. Investigators believe the man shot his estranged wife and all four children at their home early Saturday before killing himself, People reports. Family members identified the parents to NBC San Diego as Jose Valdivia, 31, and Sabrina Rosario, 29. Relatives say Enzie Valdivia, 3; Zuriel Valdivia, 5; and Zeth Valdivia, 11, were killed and 9-year-old Ezequiel Valdivia is fighting for his life after undergoing surgery for gunshot wounds. "We believe the male came over this morning, there was some kind of argument or disagreement and he used a handgun and shot his family before turning the gun upon himself," San Diego Police Lt. Matt Dobbs said Saturday.
"It is still unclear if the restraining order had been legally served, but we do believe the male was aware of it," Dobbs said. Relatives say the couple had been together since high school, but Rosario recently filed for a divorce the husband did not want. Police say they received a 911 call from the home around 6:50am Saturday, the San Diego Union-Tribune reports. Nobody was on the line, but an argument could be heard in the background. A second call from a concerned relative next door was received soon afterward. Police say that after they arrived at the home, they broke a window and entered the residence after seeing a small child covered in blood, reports the New York Times. A relative has started a GoFundMe fundraiser to help pay medical expenses for Ezequiel, who was hospitalized in critical condition. (Read more San Diego stories.)
