Lu Chuan shook his head at Chen Weiguo's confusion: "Probably didn't hear anything."
"Impossible, is the room soundproofed that well?"
Lu Chuan rummaged through the crime scene investigation photos and found a bloodstained earbud headset.
"There are bloodstains on this headset, and analyzing the pattern of the bloodstains, they should have been left by the suspect."
"Furthermore, when we arrived at the scene, music was still playing in the headset, and it was quite loud. This suggests that when the suspect committed the crime, the victim's daughter Zhang Mei was likely listening to music with these headphones in the second bedroom, which is why she wasn't aware of what was happening outside and thus didn't come out of her room."
Lu Chuan continued: "And when the suspect stabbed Chen Xue, there was no hesitation, indicating that Chen Xue was not the intended target."
"His real target was Zhang Mei in the second bedroom."
