Calgary police are investigating the disappearance of a five-year-old child and his grandparents from a home in the southwest and issued an AMBER Alert on Monday afternoon.

Police were called to a home in the 100 block of 38A Avenue SW at about 10:00 a.m. Monday by a mother who went to the home to pick up her son who was staying with his grandparents.

The three were not at the residence and have not been located despite efforts by police.

Investigators say evidence at the scene suggests their disappearance may be suspicious.

“When we went to the address and after speaking with family members, the home was not in the condition it would have typically been left in and there is some indication in the home that the occupants did not leave under their own volition,” said CPS spokesperson Kevin Brookwell.

Brookwell says the three were last seen at 10:00 p.m. Sunday when the mother dropped off her son for a sleep over.

"All the vehicles are accounted for so we have no information to go on at this time and that's the reason we are reaching out to the public if they saw or heard anything during the night that was suspicious to let us know as soon as possible," said Brookwell.
