Councillor Harvey Jones says he was shocked to hear news of the deaths of an adult and child in Troedyrhiw, Merthyr Tydfil.
No doubt everyone in the community and in the wider part of the borough will be shocked by this. It's very sad news.
Joanne Thomas and her four-month-old baby Harper were found dead at their home in Merthyr Tydfil in July. An open verdict has been recorded.
Police add there is 'no evidence to date' to suggest carbon monoxide killed the two, believed to be a mother and her four-month-old baby.
