North Carolina ? When investigators found the remains of Harmony Jade Creech’s baby body this weekend, she was inside a diaper box in the family’s attic, said Harnett County Sheriff Larry Rollins.

The statewide Amber Alert for the 11-month-old is now canceled and Harmony’s mother, Johni Michelle Heuser, 25, is being held without bail in the Harnett County jail on a charge of first-degree murder. Heuser’s other three children are in the custody of the state.

The baby’s father, Ronald Earl Creech II, just returned from a 15-month deployment in Iraq. Now, he must bury his first daughter, whom he had seen just once during a leave shortly after her birth in January.

Investigators believe Harmony had been dead for three or four weeks, Rollins said.
