The other kids mentioned are Tania Murrell (age 6, missing from Alberta since 1983), Courtney Struble (age 13, missing from Saskatchewan since 2004), and Mariam Makhniashvili (age 17, missing from Ontario since 2009).
I wish I could profile Canadian cases on Charley. But I really don’t have the time. Mariam’s case seems quite intriguing, from the headlines I’ve seen about it. She was a recent immigrant from the nation of Georgia (home of Joseph Stalin, born Ioseb Besarionis dze Jughashvili, gotta love those Georgian names) and I don’t think she spoke English well. She was also supposed to be really shy, hadn’t made any friends yet in Canada and wasn’t the type to run away. I wonder if human traffickers got her.
