A 3-month-old baby boy was killed in his Alabama home by his family’s “pet wolf,” according to authorities who have launched a criminal probe. The unidentified toddler died in the wild incident at a home in Chelsea on Thursday afternoon, Shelby County coroner Lina Evans confirmed to The Post. “It appears that the wolf or wolf-dog – they kept it as a, quote, ‘pet’ – picked up the child that was down on the floor and started playing with it, and unfortunately killed the baby,” Evans said.
