Jailyn’s cries echoed through the quiet streets of Cleveland in the dead of the night. The toddler whimpered and howled, but no one came to her rescue. Her mother, Kristel Candelario, was away on a 10-day summer vacation and had left Jailyn alone in a playpen with a few bottles of milk, prosecutors said. A neighbor’s doorbell camera captured the 16-month old’s frequent screams, including one around 1 a.m. two days after her mother left.
