Zahra Baker's biological mother told an Australian news organization that she was excited to hear that the 10-year-old girl's stepmother had been charged with murder.
"I finally heard him say that it was going to be murder two and I felt a little bit bad that I was excited," said Emily Dietrich in an interview with Australia's Channel 7. "I couldn't wipe the grin off my face."
Elisa Baker was indicted on a charge of second-degree murder Monday, more than four months after the girl was reported missing and parts of her dismembered body were found scattered across western North Carolina.
Dietrich, who gave up Zahra while suffering from post-partum depression, visited Hickory in November after Zahra was reported missing.

An autopsy reported released Monday lists "undetermined homicidal violence" as the cause of death. The report also says that Zahra's body was dismembered after she died.
"She had no place to just dispose of something that was in the way," Dietrich said of Baker.
An indictment against Baker cites aggravating factors, saying she had a history of physically, verbally and psychologically abusing Zahra, who used a prosthetic leg and hearing aids after being stricken with cancer.
Zahra's father, Adam, moved from Australia to North Carolina after meeting Elisa online.
"I want her to sit in jail and I want her to live every day of her life remembering why she's there and what she's done," Dietrich said. "She needs to sit there and rot."
Investigators say there's no evidence that Adam Baker was involved in his daughter's death, but Dietrich remains unsure.
"You can't honestly tell me that for two weeks he had no idea what his daughter was up to," she said.
Later in the interview Dietrich said, "He's not acting like a man that's just lost his daughter at the hand of his wife."
Dietrich said she had seen Zahra's autopsy, which said that several of the girl's bones have not been found, including her skull.
"I read it this morning and I literally just dropped my laptop and I ran," she said. "It's like something out of a horror movie. It's disgusting. She was a baby."
Elisa Baker is being held in Catawba County Jail. According to prosecutors, the second-degree murder charge carries a potential prison term of 8 to 30 years, depending on the criminal record of the person who was charged.
