A body was found in a room in the XXX hotel. The victim wrote an 8 on the wall before he died. The cause of death was CUSOTO poisoning.

One or three suspects, judging from the motive of committing the crime, Long Er and Eight Wolves had an argument in the room of the deceased, and the suspect was older than Mu Naiying.

Two, eight can mean most things, eight people? Eight o'clock? According to general inference, the deceased may want to write the name of the deceased directly, because it is more referential, so this 8 should be the name of the person.

Three, Murakami Shiro, since the deceased knew who the murderer was, if it was Murakami Shiro, why not just write an "eight" and use the Arabic numeral "eight"?

Fifth, in view of the fact that people generally fall to the ground after death, although the detailed process and situation of on-site investigation are not written in the title, according to the principle of "seeing things from the victim's eyes and looking back at the last thing he saw", it is likely that they are lying on the ground.

Six, the answer is obvious, and the great possibility is Ingrid Dragon II. Unlimited lyricism. Eight spans are infinite.
