Flaggers volunteered their time to help pedestrians cross busy South 152nd Street Saturday night.
In the minutes before they were to take the stage at the Highline Performing Arts Center, several cast members of the musical "Annie Junior" arrived.
Some paused for a moment near a memorial to the grandmother of a fellow cast member who never made it to the show Friday night.
The woman, described as in her 60s, was crossing busy South 152nd Street, when a driver, headed eastbound, struck her and kept going. She died where she fell.
The anguish was audible in the voice of a woman who says she arrived moments after the fatal accident.
"There were several medic units and fire engines and police cars," she said. And they just kept coming and coming. It was just devastating to see. It was hard for me."
The musical features seventh and eighth-graders from St. Francis of Assisi Catholic School in Burien. The victim's granddaughter is in seventh grade. Those who know the family say this is the latest major tragedy it has faced.
Her mother died of cancer just a couple of years ago.

"It's really something you don't expect," said the woman, whose son also attends the school.

Principal Rosemary Leifer said they plan to pray at the start of Sunday night's musical.
"That," she said, "is what we do."
