The bodies of a couple were found stuffed in a suitcase and a barrel in their Cunupia home on Monday.
Sources said the couple may have been dead for some time as they were last seen alive by relatives on May 13.
The deceased have been identified as 62-year old Kenneth Mackhan and his 65-year old wife Lilawatie, of Upper Welcome Road, off Ragoonanan Road, Cunupia.
Initial reports indicate that police visited the home of the couple after finding their abandoned Hyundai Tucson in the Central area.
When they arrived, they called out to the couple but no one responded.
Officers then entered the home and found the dead bodies.
Sources said Mackhan was a retired police officer.
Investigations are continuing.
