The Calgary Police Service has issued an Amber Alert for an 11-year-old boy who has been missing since Thursday afternoon, after the province issued an exemption to the alert for a vulnerable missing child. The Alberta Emergency Alert was sent out at 1:35 p.m. on Saturday for Parker. While Parker's disappearance doesn't meet the legislated criteria for an Amber Alert, police said the exemption was granted because of the "unique circumstances of this investigation." "Parker is a vulnerable autistic child and we are deeply concerned for his well-being given the length of time he has been missing and his specific vulnerabilities," said Insp. Rod MacNeil. Parker is neurodivergent and non-verbal and may become even more scared if confronted by strangers, according to police. The boy was last seen at his day home in the 0 to 100 block of Connaught Drive Northwest sometime between 11:08 a.m. and 11:41 a.m. on Thursday.
