"Wh… What?" After hearing Zhao Yu's astonishing conclusion, Captain Dou stammered. "Leader Zhao, you're not kidding, are you? If it's not Guo Yihang... Who else can it be?"
"Yeah... Who the heck is the murderer?" Li Qian was perplexed.
"Hum hum..." Zhao Yu sneered, then turned around and glanced at the rest of the group with his sharp eyes. He then said three words that stunned all of the people present...
"I don't know!" he said flatly.
Captain Dou wiped the sweat off his forehead and asked helplessly, "Leader Zhao, what do you mean by that?"
"I'm telling the truth!" Zhao Yu said frankly. "I really don't know who the real murderer is! But I can say one thing for sure... The murderer is not Guo Yihang!"
Everyone looked bewildered.
