But after opening the album, he discovered something very strange. Realizing that this might be a clue, he quickly shouted:

"Brother Yingsi, I've found something!"

"What did you find?"

Hattori Heiji ran over to Takashi Sosuke, who was checking the contents of another cabinet, holding the photo album, and pointed at the missing photos in the album.

"Look, there are some missing photos here. Could they be photos of the victim and the murderer?"

The missing part of the photo caught Fujiwara Yu's attention. After carefully looking through the photo, he unexpectedly found a golden hair, or to be more precise, a golden dog hair.

Veterinary anesthetic, missing photos, golden dog fur.

Fujiwara Yu's eyes suddenly lit up. He quickly approached the fabric sofa, bent down and carefully checked the dust and debris in the cracks of the sofa. Finally, he found golden dog hair hidden in the cracks... As expected, the victim, Imamura Fujiko, once had a dog at home.

"I didn't expect the murderer had dyed his hair golden. This hair should be sent to the Scientific Investigation Institute for examination, right?" Hattori Heiji, who had never raised a pet and had little knowledge in this area, mistakenly thought that this was the murderer's hair and came forward to ask.

If Fujiwara Yu didn't have experience in this area, he wouldn't have been able to quickly distinguish between dog hair and human hair. After all, everyone's hair quality is different, and even exquisitely crafted wigs can be indistinguishable from real hair.

He smiled and shook his head, put the dog hair into the evidence bag, and explained:

"It's not the murderer's, it's the pet dog's. But this clue also proves one thing: the murderer must be related to the pet dog. He is very likely engaged in a job related to pets, such as... a veterinarian."

"I see. That's thanks to the fact that this dog sheds quite a lot."

"Yeah, maybe it wants to quickly identify the murderer for its owner."
