As investigators await test results on a child's body found by a southeastern Michigan river, the mother of a missing 5-year-old girl says she's "completely innocent."

Monroe County authorities said Sunday they're pursuing leads as they wait for DNA evidence to confirm the body is that of Nevaeh Buchanan, reported missing May 24.

The child's remains were discovered Thursday next to the River Raisin.

Jennifer Buchanan tells the Detroit Free Press she "didn't have anything to do with" her daughter's disappearance and doesn't know who would want to harm her child.

Buchanan's mother got custody of Nevaeh after Buchanan was found guilty of breaking into homes to support a drug habit.

The three were sharing an apartment in Monroe, Mich.

On Friday, authorities said the body found encased in cement by fishermen belongs to a child the same size, gender and age of the missing girl and they had "reasonable suspicion" it is Nevaeh. A shirt resembling the one she was wearing when she vanished also was discovered.
