MYSTERIOUS DEATH.
Christina Christiansen Died Sunday at Her Ranch From the Effects of Poison.
On Sunday night Christina Christiansen, whos ranch is not far from Fairbank, died in great agony. She was taken with spasms while her cousin, V. Yendreson, was with her.
Assistance was sent for to Fairbank, but before it arrived she was dead. Her last words were, "Take care of my Children." The peculiarity of the case aroused suspicion and an inquest was held upon the body yesterday by Justice Duncan. No verdict was rendered, but the body was brought up to Tombstone and a post-mortem examination was held. Dr. Hamilton this morning discovered unmistakable signs of poison in the stomach of the deceased, and the coroner's jury will convene again in the morning to complete its examination into the cause of death.
The testimony before the jury did not show that the deceased had tired of life or had any motive to destroy herself. She complained of pains in her head and chest before dying. It is probable that arrests will follow the coroner's inquest.

The Christianson Case.
At 7 o'clock this evening the coroner's jury will convene and arrive at a verdict in the case of the death of Christina Christiansen. The young man, Yendresen, who was arrested last night was admitted to bail, but again arrested and held over without bail. He spent the night in jail. His friends say that he is entirely innocent and those who are well acquainted with him scout the idea of his being of such a crime as poisoning a person especially one of his own relatives. Circumstances however warranted the authorities in taking the steps they have taken.
A letter found on a shelf in the house of the deceased written in Norwegian on the reverse side of the sheets torn from a calendar was translated today. It was from the deceased to her mother in which she declines an invitation to visit her parents and tells of her trials and the outlook for the future which is not a gloomy picture.

The inquest held upon the body of Christina Christiansen, which adjourned to meet at the ranch last night, was completed there according to previous arrangement. The jury found both a majority and minority verdict. Five of them believed the deceased came to her death from the effects of arsenic: administered by A. Yendreacn, "while one man believed that the poison was administered by an unknown party."
