After speaking, Guan Lingyu walked out of the interrogation room. Although Yin Xiaofan's case had some doubts, all the evidence was against him. Without sufficient evidence to prove his innocence, he would likely face at least a charge of intentional injury.
There were no effective clues found on Yin Xiaofan. As Guan Lingyu walked, she kept thinking. Although she felt that Yin Xiaofan might have been wronged, as any sane person wouldn't attack an elderly person who had collapsed.
But every time she thought of how confident and unabashed Yin Xiaofan acted, even eating and drinking lavishly in the interrogation room, Guan Lingyu felt a surge of anger. Was he treating the Police Station like a hotel? Even if he were innocent, he should be detained for a few days to reflect on his actions.
