CAMDEN, N.C. (AP) — It’s a mystery that a North Carolina man is still trying to solve. Cornelius Williams says he went grocery shopping Tuesday night. When he returned, he found a cardboard box in his walkway, one that was emitting squeaky sounds. He couldn’t bear to look inside, so he called police. When a deputy showed up, he peered inside and found two newborn bear cubs, wrapped in blankets. Camden County Sheriff Kevin Jones says it’s not unusual to spot bears in the area — but finding them in a box was, as he put it, “a little strange.” Williams agrees, saying he has no idea why anyone would leave a pair of bears at his home. News reports say the animals have been taken to a zoo in Asheboro to be examined and cared for.
