San Bernardino shooting: Family shares photos of slain 8-year-old

School district officials said classes at North Park would be canceled for at least Tuesday and Wednesday.

The shooting left hundreds of distraught parents waiting for hours to reunite with their children.

Jeffrey Imbriani and his grandfather Ruben Gutierrez describe their experiences Tuesday, April 11, 2017, after a teacher and student were shot to death Monday at North Park Elementary School in San Bernardino, Calif. Imbriani said he was friends with Jonathan Martinez who was killed along with his teacher, Karen Smith.

"All things considered, he's in relatively good spirits", Burguan said. "Nor do we know exactly why he chose to do this at the school", the chief said.

"She was an excellent teacher", said Marie Cabreras, who has two young children at North Park and also has an older daughter who was Smith's student for two years at a nearby high school.

The students were not targeted but were standing behind Smith when her estranged husband opened fire, Burguan added.

But it's time to call yesterday's deadly shooting at a San Bernardino elementary school what it really was: domestic violence. Smith was killed immediately.

Jonathan was born with Williams syndrome, a genetic condition that affects about 1 in 10,000 people worldwide, including an estimated 20,000 to 30,000 people in the United States. The syndrome causes cardiovascular disease, developmental delays and learning delays, according to the Williams Syndrome Association. "Please continue to pray for him and also for Jonathan Martinez's and Karen Smith's families". Thank you (for) coming together.

Parents also should ask their children whether they know what their school's plan is for emergencies like this one, Nelson said.

Police said Anderson used a Smith & Wesson.357 revolver, firing 10 rounds and reloading once during the attack.

Anderson had been arrested twice in Torrance, police records show.

By mid-March, Smith had moved out of their Riverside home amidst allegations of infidelity and was living with family, including her adult children.

"She keeps telling me 'My teacher got shot, my friend got shot, '" her mother, Elizabeth Barajas, said as she clutched her daughter's blood-stained sweatshirt.

She didn't take him seriously and thought he was just seeking attention, he said. Smith has been identified by authorities as one of the people shot by Cedric Anderson, identified as her estran. "Her whole life was surrounded around kids and helping them, and helping them build a future".

"If found outside of the context of this case, I'm not sure anyone would be terribly alarmed", Burguan said.

He left no suicide note, but police found a handwritten document indicating he felt disrespected and wanted resolution, Burguan said.

A computer and phone taken from the residence will be examined, authorities said.

Unlike the phone of Dec.2, 2015, shooter Syed Rizwan Farook, which was hacked only when the Federal Bureau of Investigation hired a company to override the encryption, police do not expect to have difficulty obtaining information from Anderson's and Smith's phones, Burguan said.

Investigators are looking into what may have caused the couple to separate.

Family members posted photos of Jonathan on social media of him on amusement rides, sitting on Santa's lap and riding a horse - all of them show him flashing a smile.

"There was no indication to anyone (on) staff that he was a threat", Marsden said.

In the past, Anderson had served as a pastor at a church in the Los Angeles area, Burguan said, but most recently worked as a maintenance worker.

The Smith & Wesson revolver Anderson used Monday was purchased in MI in 1979 by someone other than him. "There does not appear to be a breakdown of security", Burguan said.

A candlelight vigil is planned for the victims Tuesday evening at North Park Elementary. All other district schools will remain open.
