Hasan Ali Gori and Mary Ray, both 50s, were found living in squalor at wetlands located off Condell Road, surrounded by scurrying rats, rusting containers, and insect-infested bedding.

The body of 89-year-old Josephine Ray was found at her home in Nenagh last Sunday.

A man and woman aged in their 50s were arrested as part of the investigation, and are currently being held in a Garda station in Tipperary.
