FORMER LANE COUNTY WOMAN MURDERED BY HUSBAND AT SALEM
Salem, Oct. 21 – Mrs. Stella Timmons, 21 years of age, a sister of Miss Edna B. Bogart of Eugene and a niece of a farmer of the same name of that city, was murdered by her husband, Silas (sh/be Cyrus) Timmons, a plasterer, who slashed her throat with a razor at 12:30 o'clock this morning. Afterward the murderer attempted to kill himself by cutting his throat with the same razor but was unsuccessful, and being under the influence of liquor, fell asleep across the bed, beside which his wife, in her night dress, lay in a pool of blood. He awoke at 7:30 this morning and secured assistance. It is believed the crime was the result of a drunken frenzy and insane jealousy, the couple having agreed before an attorney here yesterday to secure a divorce. Timmons, who is 37 years of age, will probably live. He makes no denial of the murder.
Mrs. Timmons was the daughter of Andrew Bogart and wife, both of whom have been dead for several years. They resided between Eugene and Coburg, where Mrs. Timmons, whose Christian name was Stella, and her sister, Edna, were born. Mrs. Timmons was about 21 years of age. [In fact, she was just 19.] She has four uncles, A.G. Bogart, living about half way between Eugene and Coburg; William Bogart, living close to Coburg; John Bogart, at Spokane; and Charles Bogart, living near Lebanon.
Timmons and his wife were married about two years ago. They were visiting relatives here last week and expected to come back to Eugene next week. Timmons is a plasterer and he intended working at that trade on the many new buildings going up here.
Mrs. Timmons was raised in this county. After the death of her parents, she and her sister, Edna, were left to care for themselves, and Stella had been a ward of the Boys' and Girls' Aid Society at Portland at one time. She was not a wayward girl, but was placed in that institution so she would be properly cared for. ~~END~~

IN JEALOUS RAGE C.Y. TIMMONS SLASHES WIFE'S THROAT, THEN DRAW BLADE ACROSS HIS OWN
SALEM HORRIFIED BY HARROWING TRAGEDY AS THE RESULT OF DOMESTIC DISCORD
SALEM, Ore., Oct. 21 - (Special to the Register.) Late tonight the coroner's jury returned a verdict that Mrs. C.Y. Timmons was willfully and deliberately murdered by her husband, at an early hour Wednesday morning. The evidence showed that Timmons and his wife had been quarreling almost constantly since their arrival here some weeks ago. Yesterday afternoon they agreed to secure a divorce and went together to consult Attorney Walter Keyes. The wife told her story, stating that her life had been repeatedly threatened by her husband, who drank at times and had a furious temper. Her husband did not dispute any of the allegations of the wife and the attorney told the coupe to return this morning and papers would be prepared. The couple then returned to their rooms on Cottage (sh/be Court) Street.
Timmons went out and returned late and a quarrel followed. These had become so frequent, however, that other occupants of the house paid but little attention to the racket. No screams for help were heard. This was about 12:30 Wednesday morning. At 7:30 Timmons staggered into the other part of the house where the other family is living and pointed toward the bedroom. The police were summoned and found the woman dead in bed with her throat cut from ear to ear and with the floor and bed covered with blood. Timmons was only partly dressed and his throat was badly slashed. He was covered with blood from head to foot. He is now in the hospital and will live although his windpipe is severed and badly injured. Information will be filed tomorrow morning charging him Timmons with first degree murder.
Mrs. Timmons was a Eugene girl, whose maiden name was Bogart. She has an uncle, aunt and sister living there now. Before marriage she was employed in Eugene stores. She went from Eugene to Oswego, and then to Toledo, Washington, where she married Timmons, who is a plasterer, aged 37. The dead woman is only 19. One child died some time ago. None are living.
The verdict of the coroner's jury leaves but little room for the plea of insanity or drunkenness, as the evidence showed he was not drunk when the crime was committed. Timmons was insanely jealous of his wife, which is thought to have been the motive.
NEWS CONVEYED TO MR. BOGART
Chief of Police Farrington received word of the awful tragedy yesterday morning and at once telephoned A.G. Bogart, uncle of Mrs. Timmons, but found that he was in the city. The news was broken to him and he was heartbroken upon hearing it. Miss Edna Bogart, sister of the murdered woman, also learned of the news with horror. It was determined to have the body brought here and funeral announcements will be made later.
Mr. and Mrs. Timmons were in Eugene a week ago and visited the Bogarts and it was determined to go to Salem and close up their business there and return to Eugene, where Timmons was to work at his trade—plastering. It was learned yesterday that Timmons would frequently get on great sprees and never failed to treat his wife inhumanly when he did so, and friends of the woman were informed by a fellow workman that her life was in danger on such occasions.
Mrs. Timmons was the daughter of Mr. and Mrs. Andrew Bogart, who lived between Eugene and Coburg, where their two daughters were born. [Andrew and Martha Bogart also had a son Charles Walker Bogart, who was the eldest of their three children.] They died [both from tuberculosis] while the girls were both young and Stella, who afterwards married Timmons, was placed in the care of the Boys' and Girls Aid Society at Portland, Edna remaining with her uncle A.G. Bogart. William Bogart is another uncle living near Coburg. ~~~END~~

Final Note:
C.Y. Timmons was tried and convicted of murdering Estella (Bogart) Timmons. He was executed in Salem by hanging on February 26, 1909. He was buried in an unmarked grave in Lee Mission Cemetery in Salem.
