Countess Poison Case

It was a cold and humid morning on November 26, 741 in the continental calendar. The Montra Empire Tipisa Regional Police Station received a report. The reporter was one of the local dignitaries, Count Yavin der Dan Horitger. The count claimed that when he returned home early that morning, he found his wife, Countess Verity Kuro dan Holitger, dead on the bed in their bedroom. After preliminary investigation, the police found that the countess died of poisoning. All signs at the scene pointed to her suicide, except for one thing - no equipment used to contain the poison could be found. Further investigation made Count Horitger, who planned to marry the richest local banker Nikolai Vezni Oplin in order to consolidate his position, become the biggest suspect. On December 7, the District Attorney of Tifisa ordered the arrest of Count Yavin del Dan Horitger and filed an indictment with the Court of Lords. On December 10, the day of the court hearing, the count was found dead in prison. Some people say that the count discovered his conscience and died of guilt; others think that the ghost of the countess who died unjustly came to demand her life. But no matter what, everyone believed that the count's death was deserved. The above are all already known to the public, and what I want to tell here are the unknown things in this story. Whether you believe it or not is up to the readers themselves. Conception:
