While Richard was going to the forensics office, a phone suddenly called him. "Richard, where are you now?"
Richard was in a hurry, but when he found out that the forensics department had contacted him, he immediately stopped in his tracks. He wanted to listen carefully to the forensics department's important matters discussed in this case.
"What's wrong? is there any other information I should get?" asked Ricard with his head full. He did not know whether his investigations tonight would come to fruition or not, but he had gone a long way tonight, coming himself to the lion's den and causing trouble there; he was worried that he would no longer be able to investigate the cigarette butt, especially since tonight he had shown his face to the people there.
"Yes, how did it go?" Richard asked. Finally, he rubbed his temples.
