Key issues
1. Why has the investigation taken so long?
Because it involves cross-border judicial cooperation, according to prosecutors.
2. What was the suspect's motive?
Lyu Yueting argues that he poisoned the dumplings to bring the management's attention to his request for a pay raise and he did not intend to harm anyone. Prosecutors reject the argument as “nonsense”.
3. Did Lyu foresee the serious consequences?
Lyu says he diluted pesticide with drinking water. Prosecutors say that does not make any difference.
4. What was Lyu's attitude afterwards?
Lyu said he wrote three anonymous letters to his manager to warn him about toxic food after he poisoned the dumplings. Prosecutors say that Lyu named two of his colleagues as culprits in the letters, which they say misled the investigation.
