Jonathan Martinez, an 8-year-old student in Smith's class, was also shot and died on the way to a nearby hospital, an unidentified 9-year-old student was also shot but is now in critical condition.
"It appears that he had been making efforts to contact her and to have her come back home, and she was resistant to that", Burguan said. The man who fatally shot his estranged wife and a student in her San Bernardino elementary school classroom before killing himself had threatened her when she moved out of their house, authorities said Tuesday.
Police said the children shot were not targeted and were likely struck by accident.
The superintendent said the Martinez family wanted to honor Jonathan's memory by getting the word out about Williams syndrome. The pro-gun control group Everytown for Gun Safety reported in 2014 that more than half of women murdered with guns in the USA are killed by domestic partners, and that from January 2009 through June 2014, almost three of five mass shootings (at least four people killed or wounded) involved an act of domestic violence - crimes that rarely resonate beyond the communities in which they occurred. He went to her classroom and "without saying anything" shot her with a large-calibre revolver, Mr Burguan said.
Just weeks before the shooting, Anderson had professed his love to Smith in a series of social media posts, including one that called her an "angel".
Investigators say he was not seen with a gun until he entered the classroom and fired 10 shots.
San Bernardino Unified School District Superintendent Dr. Dale Marsden said the North Park campus will remain closed until Monday, April 17.

"The first week after a woman makes the courageous decision to leave an abusive relationship is often the most unsafe week of her life", said Bryan Pacheco of Safe Horizon, an organization that supports victims of domestic violence. "We are grateful to law enforcement and school leaders for their quick response to the tragedy", said a joint press release by the offices of Assemblymember Eloise Gómez Reyes and State Sen.
A 9-year-old student who was wounded in the shooting remains hospitalized Tuesday.
"By all accounts Jonathan Martinez was a happy child", he said. "Her whole life was surrounded around kids and helping them, and helping them build a future", Cabreras said.
"She tried to hide it, but it's hard for her so we're just here for her trying to help her cope", Johnson's sister, Mercedes, said. She said the long wait was "frustrating but also understandable".
"She thought she had a wonderful husband, but she found out he was not wonderful at all", Sykes told the Los Angeles Times. She's visiting God. So is Jonathan. "They are extremely sociable and experience the normal need to connect with others; however people with Williams syndrome often don't process nuanced social cues and this makes it hard to form lasting relationships".
