Calgarians journeyed Thursday to a north end park to hug, cry and honour the memory of an 11-year-old boy. The makeshift memorial for Parker has grown one flower, candle and stuffed toy at a time on a footbridge in Laycock Park. We also understand that autistic children can face additional risks, particularly those who are prone to wandering, are non-speaking, or may be unable to ask for help when they are lost,” they said. “Parker’s death has also exposed a serious gap in how Canada responds when vulnerable children go missing.” The National Autism Network said emergency alert systems and first-responder training need “urgent change” for vulnerable children and their families.
