Crime scene: 162 mystery solving puzzles to find out who the murderer is

Chapter 161 The Poisoning Case in the Restaurant
One day, A, B, C, and D are dining together in a restaurant.Suddenly, Ding yelled: "Someone poisoned the food!" and fell to the ground dead.After receiving the report, the police rushed to the scene and summoned the three people who had dinner with Ding.Statements from all three were recorded at the police station.Because everyone who was interrogated told two truths and one lie, it was difficult to get to the bottom of the case for a while.

A said: "I didn't take poison." "I was sitting with C." "The full-time waiter is serving us."

B said: "Ding is sitting across from me." "Now we have a new waiter." "The waiter did not poison Ding."

C said: "B did not commit a crime." "The waiter poisoned D to death." "The murderer is among us."

A lied before saying "the full-time waiter is serving us".If you are a policeman, smart reader, can you judge who is the murderer based on these confessions?

[Answer] C is the murderer.

According to the prompt, because A said a lie before saying "the full-time waiter is serving us", it can be judged that the sentence "the full-time waiter is serving us" is the truth.Then, "Now we have a new waiter" in B's statement is a lie, so it can be concluded that the other two sentences he said are true.So B is not the murderer.Looking back at A's statement, "I sat with C" is a lie, and "I did not poison Ding to death" is the truth.To sum up, neither A, B nor the waiter is the murderer.So C is the murderer.
