The biological mother of Zahra Baker, the 10-year-old Hickory girl who was murdered in late 2010, has told an Australian TV network that she has no idea what happened to her daughter's remains.

Emily Dietrich told 7 Network in Australia that she has not heard from Adam Baker, Zahra's father, since he returned to his native Australia about two weeks ago.

"I don't have her remains, and I don't even know if she's been buried, at this point," Dietrich told the Australian TV news network.

Zahra Baker was born to Dietrich and Adam Baker in east-central Australia, but Dietrich suffered from depression after the birth and gave up custody of the girl to Adam Baker. Zahra was reared by Adam Baker's family and moved with her father to the United States in 2008, after Adam Baker met Elisa online and married her.

The family moved to Caldwell County, where Elisa is from, and then settled in Hickory in summer 2010. Zahra Baker was last seen in late September 2010, and her remains were found in early November. Police said she was murdered.

Elisa Baker entered a guilty plea to second-degree murder late last year and was sentenced to 18 years in prison. Adam Baker was not charged in the case, although his plans to return to Australia were delayed because he faced several misdemeanor and felony charges in Catawba and Caldwell counties. Most of those cases were settled last month.

On Monday, Baker's attorney, Shell Pearce, told reporters that his client had been deported by U.S. officials to Australia about 10 to 14 days earlier. Pearce said Adam Baker had taken Zahra's remains with him and planned to bury them in Australia.

On Tuesday, Dietrich said she has no idea where Adam Baker is, or if Zahra's remains have been buried. Pearce said he did not want to reveal where Adam Baker had gone in Australia.

When asked if she would like to share the ashes with Adam Baker, Dietrich said, "The way that her murder was carried out, splitting her ashes just seemed so tasteless. She's already in pieces."

Dietrich said parts of her daughter's body were never recovered.
