Students at Independence High School in Glendale head back to campus Tuesday with two of their classmates missing.
Glendale Police say two 15-year-old girls were killed in a murder-suicide Friday morning.
Investigators say another student shot and killed May Kieu. Police are choosing not to name the shooter at this time.
A memorial of flowers, balloons, candles, and posters sits on the edge of campus. Since Friday, students, teachers, and people in the community have gone there to show their support.
A GoFundMe account has been set up to help with Kieu's funeral expenses. If you would like to help, you can donate here.
