The body of a recent graduate of Coppell High School was found early Friday suspended from a swing set at Lee Elementary School on the city's east side, officials said.
The girl, Emily Coker, 18, graduated last year, said Tamerah Ringo, spokeswoman for Coppell schools.
A jogger saw her body before classes started at the playground of the school, 113 Samuel Blvd., and called 911, Ringo said. Emergency crews responded, but the girl could not be saved, Ringo said.
A statement posted on the school district's Web site described it as an accident, but Ringo said it will be up to the Dallas County medical examiner's office to determine the exact cause of death.
Never miss a local story.
Coker's mother teaches at a Coppell middle school and she has a sister at the high school, Ringo said.
Parents were being allowed to pick up their children from school, but none of the campuses were actually closed, Ringo said.
Meanwhile, she added, grief counselors were being offered to students, parents and staff because the death was sending "ripple effects" throughout Coppell.
"It's a small community," she said, "so it affects not just the campus where the incident occurred, but also the campus where her mom worked and the campus where her sister attends."
The swing set was going to be removed from the playground either late Friday or sometime Saturday, Ringo said.
