The shooting at North Park Elementary, the latest of dozens of USA schools traumatized by armed intruders in recent years, reopened debate about what educators can do to safeguard students against mounting gun violence. A husband opened fire on his wife Monday in the elementary school. But after they Wednesday and he moved into her Riverside home, another side of her new husband emerged. Her family also told police that Smith may have not taken those threats seriously, because "she thought that he was reaching out for attention", he said.

The couple divorced in 1997.

Police said they did not find a suicide note in their search of his home Monday in Riverside.

"Children were just a part of her life".

Mary Fields, a fellow teacher, said Smith loved kids. CNN affiliate KABC showed footage of school buses that were being used to take students to Cajon High. He killed her and one of her students before killing himself.

San Bernardino, a city of 216,000 people about 60 miles east of Los Angeles, was the site of a December 2015 terror attack that killed 14 people and wounded 22 others at a meeting of San Bernardino County employees.

Children with the syndrome tend to have striking verbal abilities and an affinity for music, Marsden said.

Eight-year-old Jonathan Martinez died shortly after being airlifted to Loma Linda Hospital, according to Burguan.

Toys, teddy bears and flowers could be seen at a growing memorial for the victims outside of the elementary school Tuesday.

San Bernardino police have said nothing of what might have motivated Anderson to open fire in the special-education classroom at North Park Elementary School on Monday.

Burguan confirmed during a Tuesday press conference that a family member told investigators Anderson made an allegation of infidelity against Smith and that she had mentioned his behavior was odd.

Anderson has four adult children, all of whom have been accounted for, Burguan said.

An analysis of homicide data from 2013 by the Violence Policy Center says that black women were murdered at two and a half times the rate their white female counterparts were, and that 56 percent of these black women were shot and killed by current or former intimate partners. Burguan said 10 rounds were fired, with one reload as the gun holds six rounds. He didn't provide more details.

The two had dated for four years and got married in January.

He was at work when he heard about the shooting from the boys' mom, who works for the school district.

School district officials say classes at North Park Elementary are canceled for at least Tuesday and Wednesday.

Counselors have been made available at a nearby school for Smith's students and coworkers. The gunman, Cedric Anderson, then fatally shot himself.

Another 9-year-old standing behind Anderson was shot, but is in stable condition. San Bernardino Police Chief Jarrod Burguan told the Los Angeles Times that the couple was "estranged" after just a few months of marriage and that Anderson's criminal record included arrests for weapons possession and domestic violence in a previous relationship.
