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.Read the full story ›
A mother and her baby daughter who were on Social Services' radar had been dead for at least a week before their bodies were discovered, an inquest has heard.
Joanne Thomas was found in her bed alongside four-month-old Harper at their terraced home in Troedyrhiw, South Wales, last July.
Aberdare Coroner's Court heard concerns had been raised weeks before, after 27-year-old Miss Thomas failed to take Harper for her injections.
A social worker told acting coroner Andrew Barkley he tried to visit Miss Thomas on three occasions before their bodies were found, as well as sending out letters and attempting to contact her family.
The bodies were eventually formally identified via dental records and DNA testing - with a top pathologist saying it was "impossible" to say who had died first.
Police later ruled out foul play, as well as discounting the possibility of carbon monoxide poisoning - after "slightly raised levels" were found in the blood of smoker Miss Thomas' blood and her baby.
A coroner was told Miss Thomas regularly complained of feeling unwell in the weeks leading up to her death and may have been vomiting blood.
The Deputy Minister for Tackling Poverty, Vaughan Gething, will highlight more than £20 million of Welsh Government investment over the next two years to support Merthyr Tydfil and Rhondda Cynon Taff's most deprived communities.
Speaking at a special event looking at efforts to address poverty in south Wales, he will outline the number of initiatives in place to help the most vulnerable and improve their life chances.
The Welsh Government is facing unprecedented cuts. By 2015 -16 our budget will be nearly £1.7 billion less than it was in 2010 - 11.
Despite this, we are determined to invest in our most deprived communities to help improve health, education and life chances.
That is why we have a multi-million pound investment support package in Merthyr Tydfil and Rhondda Cynon Taff. We are committed to helping people have a better chance of finding work and supporting parents facing the reality of managing on tight budget.
We know that the UK Government's welfare reform agenda is hitting hard with less help for hardworking parents as cuts to tax credits, cuts in help with childcare costs and the bedroom tax really bite.
The Welsh Government's approach is based on a different set of values and priorities. We know that to make the biggest possible difference to people's lives all of us across the public and voluntary sector need to work together much more effectively.
