PHOENIX — A week after a 16-year-old student was fatally stabbed at Maryvale High School, two public figures allegedly tried to bring a weapon onto campus, according to district officials.
Arizona Rep. Lydia Hernandez and her daughter, Cassandra Hernandez, allegedly tried to smuggle a boxcutter into the school on Monday, according to the Phoenix Union High School District.
Hernandez both represents Arizona’s 24th Legislative District and serves as the governing board president of the Cartwright School District. Cassandra was elected in November to serve on that same governing board.
“The Maryvale High School Safety Team secured the box cutter, and a team member escorted both individuals out of the office and off-campus,” the district said in a Wednesday announcement.

The Phoenix Union High School District said it might pursue legal action against the pair for their alleged actions on Monday.
“We will pursue all legal options, including pressing charges and trespassing the individuals from coming back to our campuses,” the district said in the announcement.
School officials accused Hernandez of filming herself and her daughter Cassandra entering through the detectors and activating alarms. The state lawmaker also recorded the safety team and asked questions about the system settings, according to the district.
“An immediate secondary search took place on the bag believed to be owned by Cassandra Hernandez, and a boxcutter was found inside,” according to the announcement.
The security team confiscated the item, at which point Rep. Hernandez allegedly said she was testing the weapon detection systems.
The school official who escorted the mother and daughter had to ask them to leave multiple times, according to school officials.
City councilmembers call on mother and daughter to resign after controversy
Now, Phoenix City Councilmembers Betty Guardado and Anna Hernandez are calling for the two women to resign from their positions.
“Their actions disrupted the fragile environment at Maryvale High School, were a blatant disregard for safety and school protocol, and were gravely insensitive to the students, families, and school staff still mourning the Maryvale student who died last week,” Guardado and Hernandez said in a Wednesday statement.
“The choice to target a school still reeling from trauma speaks volumes about their judgment and priorities as leaders. Such actions jeopardize the safety of students and staff alike, showing an alarming lack of responsibility and failure as public officials.”
