Four photos taken by the little girl before she died. Please judge who is the murderer.

The first little brother is the murderer!

Reason:

1. The photos of four men are the original pictures, which are not only the reference evidence of counterfeiting and PS, but also the theoretical basis. Only this real original photo is conclusive evidence.

2. Four photos of the little girl and the man, three are fake, one is real, and it is really the last photo of the murderer and the little girl.

3. Then only the last photo of the murderer and the little girl and the photos of four men are left as the creative material of three fake photos. In other words, the elements in the three fake photos all come from these two photos. Then, having that photo that can't be faked is the key! ?

The hand on the right shoulder of the little girl is the key, and it is the necessary action for the murderer to control the little girl to take a photo with him, otherwise the little girl will run away.

5. Find out the flaw of the hand and pay attention to the hand on the right shoulder of Little Loli. There are four different hands in the four photos, but only three hands holding the shoulders in the original photos of four men are the hands of long-sleeved men holding the fat man's shoulders; Fat man grabbed the little brother's shoulder by the hand; Yellow hair grabbed the fat man's shoulder by the hand; But I can't find my little brother's hand to grab someone's shoulder. This is the key!

6. Explain that the photo of Xiao Ge can't be faked, because there is no hand grasping the shoulder, but there is a hand grasping Li's shoulder in the photo of Xiao Ge and Li, so he must take a second photo to fill this vacancy, and he is the last person to take a photo with Li. The photos of my little brother and little loli are real photos, and the other three photos are forged according to this photo.
