Parent: 'Just pray for our kids'
Sadie Baze says her daughter, Shana Fisher, was one of the students who lost their life in the shooting yesterday. 
She tells CNNís Nick Valencia that she keeps expecting her daughter to walk through the front door ìbut sheís never going to walk through the front door again.î 

Baze says for the last four months the alleged shooter, Dimitrios Pagourtzis, had been making advances towards Shana, asking her to date him. 

A week ago, in the middle of class, Shana stood up and told Pagourtzis she wouldnít go out with him, Baze said. 

Pagourtzis previously dated Fisherís best friend and her mom told her previously ìyou donít date your friendís exís.î 

Baze believes the incident embarrassed the gunman so much that he targeted Shana

Not even a month ago, students at Santa Fe High School took a stand against gun violence by walking out of their classrooms in solidarity with their peers across the nation.

With signs that read “Santa Fe High School SAYS #NeverAgain,” they sat outside for 17 minutes of silence.

Today, the same students were left reeling from a shooting at their own school.

Nine students and one teacher were killed, 10 others were wounded, a law enforcement official told CNN.
