PHILADELPHIA (AP) — Police say three seventh-graders were taken to a hospital from a west Philadelphia elementary school after ingesting treats that may have been laced with an unknown substance. Police say they were called to Martha Washington Elementary School shortly before 11 a.m. Monday, where a 13-year-old girl reported feeling lethargic after consuming the Rice Krispies treats. She is in stable condition at Children’s Hospital of Philadelphia, as were two other girls also taken there.
