After a moment, Jiang An analyzed and said, "If anything special happened yesterday, it might be that we found the murder weapon at the scene."
"The murderer also paid particular attention to that murder weapon."
Upon hearing what Jiang An said, others began to recall.
"Indeed, that fruit knife was only discovered yesterday afternoon."
After thinking for a while, Zhang Yean said, "Are you suggesting that Zhang Biao discovered we found the murder weapon under the iron can, feared his crime would be exposed, and temporarily chose this switch-and-hide method to fake his death and evade the investigation?"
Jiang An looked around, "I think this possibility is very likely."
"Because if the murderer is Zhang Biao, the murder weapon came from here, and Zhang Biao's fingerprints would definitely be left on the knife handle."
After saying this, the others nodded in agreement.
