Autistic children and adults are prone to wandering and becoming lost, sometimes with limited communication skills. Sometimes, it ends well as it has for :
As reported on the CBC :
"An 18-year-old with autism is safe after she disappeared for nearly 10 hours in bitter cold.
Jennifer Graves-Smith vanished after leaving her school, Halifax West High, at about 3:30 p.m. AT on Tuesday. She was reported missing when she failed to turn up for her bus ride home.
Halifax Regional Police said the teen wandered near the school for hours and ended up in the lobby of a nearby apartment building just after 1 a.m. Wednesday."
