CALGARY- Police are appealing for help from the public, after a five-year-old boy and his grandparents vanished.
Around 10 a.m. on Monday, police were called by the boy’s mother from a home in the 100 block of 38A Avenue S.W. where the grandparents live. She had shown up to pick up her son, but no one was home.
Police say evidence found in the Parkhill home 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 typically would have been left in,” said Kevin Brookwell from the Calgary Police Service.
