The sudden death of a Danvers toddler has left a family searching for strength and has rocked a fire department to its core. Kayla Rose Caron was just 18 months old when she died. Her father and two of her uncles are firefighters in town. “When I think about what they’re going through it’s tough,” Fire Chief Robert Pyburn said. “This is just like a perfect storm this just doesn’t happen but it did.” One of the girl’s uncles was among the first to arrive on that heartbreaking scene last week. There was no saving her, but thousands of people in the community are hoping to honor her in a very symbolic way. Kayla’s mother had taken her shopping earlier in the day and several days earlier they had been to see the sunflowers at Colby Farm in Newbury.
