Adelma Margaret O’Mara was born in April 1932.  Whilst growing up, it was noticed that she struggled with her schooling so received only a basic education. It was recognised in her later years that she suffered from dyslexia.

Miss O’Mara lived in Maylands with her mother in a weatherboard house with sections of asbestos on the side and rear. It was located between two other homes and was directly behind the Maylands Hotel on Clifton Street.

She was a frail woman and like her mother was a total abstainer and did not attend hotels and pubs. She had no male friends.

Miss O’Mara was capable of travelling to the city to do shopping by herself, however, her mother usually prepared a detailed shopping list along with the correct amount of cash.

Miss O’Mara was also able to go by herself to the local shops and would often go many times a day. She was well known by locals and shopkeepers. She was a strict Catholic and regularly attended the local Catholic Church.

The O’Mara’s had occupied the house for approximately 40 years and the family was well known among the older residents of the area.


Around 8am on Friday 24 December 1982 Miss O’Mara’s mother went to her bedroom and on opening the door saw her daughter lying on her back on her bed, with the top part of her head under the headboard and a pillow over her face.

Investigations revealed that Miss O’MARA had died by the use of violence to her face and throat.

The person or persons responsible for Ms O’Mara’s murder have not yet been identified.
