[burning the brain to see the reasoning problem] The old man died strangely, and relatives and friends cried around the bed, and the real murderer was among them. Which is the real murderer?

As can be seen from the picture, the only person who cries with his back to the old man is E, and people will instinctively avoid it when they are guilty or afraid to face it. Turning your back is a common evasive and evasive posture. God bit his finger and made himself cry, fearing that people around him would observe his expression. As can be seen from the picture, an earplug in the doctor's stethoscope is missing, so where is the earplug? The normal answer is that the doctor colluded with e. The earplug of the stethoscope should be in the old man's ear, but I didn't find it in the old man's ear in the picture, but how can I prove that E colluded with the doctor? From the picture, you can see that E's right index finger is pressed near his ear. When normal people cry, they have never seen anyone crying according to their ears, so breaking E is to remind the doctor that the stethoscope is still in the old man's ear. It is said that E colluded with the doctor to kill the old man.

This is someone's reasoning! Think a lot? But reasonable is good!
