Brittney Sierra, at left, and Calvin Melvin, at right, were jailed on child-neglect charges following a Hallandale Beach police investigation into the disappearance of the parents' baby, Dontrell, at center.
The baby was five months old when he vanished in July 2011. But no one realized the boy had permanently disappeared until January this year, the same month his bones were unearthed from a backyard.
