Isaac Henry Thurston, 69 years, committed suicide in Hawthorn yesterday in the a most determined manner. Deceased resided with his son-in-law, Mr Wm Parry accountant, Wakefield Street. Mr Parry was awakened shortly after 5am by the sharp crack of a discharged rifle, the noise apparently coming from the adjoining bedroom, occupied be Mr Thurston. He hastened to the room, and then found his father-in-law lying on the bed lifeless, shot through the head. A Winchester sporting rifle lay alongside him on the bed. One end of a piece of string was attached to the trigger; the other was tied to the foot of the deceased. Evidently the old man had laid down on the bed, deliberately placed the riffle to hes head, and pulled the trigger with the aid of the string looped round his foot. Dr Boake was called at once, but pronounced life extinct. Deceased had for years been a martyr to rheumatism. The doctor recently advised him to go into a hospital for treatment and this seemed to have affected his spirits, although his conduct on the previous night led to no suspicion that he intended self-destruction. The body was removed to the Morgue.
