The meeting ended.
Jiang Yuan followed the head of the fourth team, Pang Jidong, straight to the evidence room to collect the main pieces of evidence, namely the entire clothing of all four victims.
Besides that, the forensic science technicians of the day also collected some other evidence from the victims, including tiny grass and tree leaves, soil and fibers found in the victims' nails, and lubricant residues on the victims' bodies and underwear, etc., but none were decisive pieces of evidence.
Jiang Yuan didn't take these pieces of evidence and returned to the laboratory with just the clothing.
