Police say the deaths of a mother and baby from Merthyr Tydfil are not being treated as suspicious.
The bodies of Joanne Thomas, 27, and her four-month-old daughter Harper were discovered on Wednesday at an address in the village of Troedyrhiw.
Post-mortem examinations carried out to establish how they died have proved inconclusive so far and officers are awaiting the results of further tests, but there do not appear to be any suspicious circumstances.
A file of evidence is now being prepared for the Coroner.
Officers piecing together Joanne’s last movements still want to hear from anybody who think they may have seen her in the weeks leading up to Wednesday 3rd July.
Specially trained officers continue to provide support to the family at this difficult time.
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.
