Officer Zhang remained unmoved, his arms crossed over his chest as he leaned against the wall. "We've already checked with the local authorities. There's no record of your sister being reported missing. And as for your mother, an autopsy has been arranged as per standard procedure. But until the results come back, there's nothing more we can do."
At that moment the door to the dimly lit interrogation room creaked open. Officer Zhang looked up to see a tall police officer entering, a folder clutched tightly in his hand.
The tall officer cleared his throat, drawing everyone's attention. "We've just received the results from the autopsy," he announced. "The report confirms that Xia Sirong, Mr. Xia's mother, died of natural causes—a heart attack."
