The pair were found with no obvious signs of injury and a post-mortem examination will be conducted to understand how the tragedy occurred, as reported by the Daily Telegraph.

Ms Carrig has reportedly lived inside the home for several years with her daughter, who requires full-time care.

Ms Carrig’s best friend Samantha Thomas-Barber described the mother as ”caring” and “thoughtful”.

“A true treasure and warrior … she was the best mumma to her family,” she said, according to the Daily Telegraph.

A neighbor, who has lived on the street her entire life, said she was “devastated” to learn the mother and daughter had died.
