OSAKA (Kyodo) A 23-year-old mother who was arrested Friday after the rotting corpses of her two toddlers were found at their apartment in the city of Osaka has told investigators that she wanted time for herself, police sources said Saturday.

"I thought about a week later they might be dead," she was quoted as telling the investigators. "I didn't feel like I should return home to save them," she added.

Autopsies found that the children died around June after several days without food, although an exact cause of death could not be determined, according to the police.
