A grieving mother in Northern Ireland is pleading for the public's help in tracing the final moments of her gay son.
Terry McCartney, 42, was found dead at his flat in Londonderry at 10am on 6 February.
A well-known gay activist, McCartney was involved in a fight with a group of men hours before his death, during which he was punched to the ground.
After the post-mortem, police are not treating the death as suspicious.
