A woman who was found killed at a flat in west Belfast may have lain undiscovered for two years.
Marie Conlon’s body was discovered on Friday by police who found she had been dead ‘for some time’.
Police in Northern Ireland had forced entry to her Larkspur Rise home and discovered her dead in bed.
Ms Conlon, 68, was last seen in January 2015 and police believe her murder occurred then.
Detective Chief Inspector Alan Dickson said: ‘Authorities were alerted on Friday after concerns were raised about the welfare of 68 year old Marie Conlon.
‘Officers forced entry to her Larkspur Rise home and discovered her deceased in bed. It was apparent that she had lain undiscovered for some time.
‘A post mortem examination was carried out and the results suggest that the death may have been suspicious. Further testing is due to take place.
‘Detectives investigating the circumstances of the death have established that the last known sighting of Ms Conlon was in January 2015.
‘It is our belief, supported by the medical evidence, that her death may have occurred at around this time.’
Police have launched a murder investigation and a 23 year old man has been arrested on suspicion of a number of offences including murder.
He was detained in the west Belfast area yesterday and remains in custody at present.
Anyone who believes they may have information is asked to call police on 101.
