The North's Social Services Minister has asked Henry Toner to return to the Western Trust to verify that all recommendations from his report on the Lammy fire tragedy have been implemented.
This week an inquest ruled that Arthur McElhill killed himself and six members of his family because his partner had threatened to leave him.
A report by Henry Toner QC criticised how different agencies communicated information about the type of man McElhill was.
The report made 63 recommendations in 2008 and Mr Toner has been asked by Health Minister Michael Mc Gimpsey to verify they have now been implemented.
Meanwhile, the Chairman of the NI Health Committee has said it will announce in the New Year whether or not to seek a public inquiry into the tragedy. Jim Wells said they would take their time to make the "right decision".
