Every student at lapped the building Friday for an hour (or 30 minutes for the younger ones) to raise money for the American Cancer Society.
Murphy School's Annual Cancer Walk began in 1999, after school psychologist Judy Davids lost her battle with breast cancer.
Davids is remembered as "a professional who cared about others and about doing her very best for children," "an inspiration to her colleagues," "always an advocate for children and families," "a consummate collaborator."
In a 1998 newsletter of "School Psychology in Illinois," a administrator wrote: "We have a better school district as a result of her dedication and leadership."
Since then, students have raised money through pledges each year and circled the school building. Each wears a tag and receives one mark for each lap completed around the school.
Students usually raise about $2,000 for the American Cancer Society each year, according to school officials.
The school also posted a bulletin board with names of Murphy staff and students who have been affected by cancer.
