During his father's illness and subsequent death, Austin began to see signs of similar mental illness in himself, now thought to be Alzheimer's disease. Austin was living and working in Seattle as a printer at the Puget Sound Dispatch when he was severely injured in a fireworks explosion on July 4, 1872. The explosion severely lacerated the lower part of his face, removing all the incisors from his lower jawbone. He had spent most of his life in San Francisco and many years traveling to seek medical treatment to restore his health, while retaining a real estate office in Seattle. Upon returning to Seattle in 1889, he made plans to erect a large brick building on the property he inherited just south of his father's hotel, since renamed the Bellevue House. On April 23, 1889, he took his nephew, william M. Coffman, on a buggy ride to share his plans. The next morning, his demeanor had changed and he was suffering from indigestion. He went to his realty office as usual, locked the door behind him and shot himself in the head. A neighboring merchant heard the shot and rushed across the street to tell a pharmacist that a murder must have occurred. After summoning a Doctor, several men broke down Bell's door to find him dead by his own hand. He was 35. A suicide note to Eva was discovered stating that he did not consider life with poor health worth living and expressed sorrow that he must take this way out.
