Pink was Tekau Rasayon’s favorite color.
Rasayon was jogging on the track when she collapsed, school officials said. The school nurse and an ambulance were called to the scene. Rasayon was taken to Southern Maryland Hospital, along with her mother, and was later pronounced dead.
The school, which has about 850 students, started the day on Thursday with a moment of silence in memory of Rasayon.
Students were planning to walk around the high school track and release balloons to honor her in the afternoon.
School officials said Thursday that a cause of death has not been determined. Counselors were at the school to offer support.
