It came so quickly.
Brother Long was stunned for a moment and went to open the door with his phone.
There were many fully armed police officers standing outside the door.
"Please come in, sirs," Brother Long said with a smile.
"We won't go in," said the leading policeman. "You said on the phone that you knew who the murderer was. How did you know?"
"Sirs, please wait a moment."
"Dr. Chen, the police are here. Tell me who the murderer is," Brother Long said to the screen.
"The murderer is right in front of us," Chen Yu said unhurriedly. "It's none other than you."
"Me?"
Brother Long's mouth instantly fell open, and his expression was as if he had seen a ghost.
The police officers who came to collect clues were also shocked by this sentence.
He immediately placed his hand on his waist.
"Chen, are you kidding me?"
"If I'm the murderer, why would I report myself?"
