A family has marked the 50th anniversary of the shooting of a father and daughter at their home in south Belfast.

Jim Kyle, 61, and his daughter Rosaleen, 19, were killed when a gunman opened fire at their house in Ormonde Park, Finaghy, on September 25, 1976. Mr Kyle was a bank manager at Trustee Savings Bank (TSB) and Rosaleen had recently graduated from Methodist College Belfast and had been accepted to study dentistry at Queen's University Belfast.

Terence Kyle, a surviving son, said his father and "beautiful sister" were "murdered because of hate but they will always be remembered with love". He added that they mattered and no one had the right to extinguish their lives.

At a 1977 inquest, detectives said the shooting was likely a case of mistaken identity because Mr Kyle was listed as "chief inspector" in a Belfast street directory, leading the killers to believe he was a police inspector. In fact, the title referred to his role as chief inspector of bank branches, though he had recently been promoted to general manager.

The Kyle family lived in Ormonde Park, described as a mixed and peaceful residential area. On the evening of the attack, Jim, his wife Elizabeth, and Rosaleen had just finished tea. Elizabeth had gone to bed with a cold. When the doorbell rang, Rosaleen answered and a young man asked to see her father. Jim was shot in the hallway, and Rosaleen was shot when she rushed to him.

Jim died in hospital on October 28, 1976. Elizabeth remained living in the house until her death in 2013, saying she could not leave because she wanted to stay close to her husband and daughter.

There were unconfirmed reports that the Irish National Liberation Army (INLA) was responsible for the murders. No one has been convicted.

The family's story is one of many from the Troubles in which families continue to live without answers or justice.
