After realizing that their daughter’s life could be saved, the parents of Ryleigh Hillcoat-Bee, a three-year-old who passed away from a rare disease, are furious.

The young girl had rhabdomyolysis, a condition that causes muscles to break down.

Complications from the illness, which affects one in 200,000 people in the UK, caused her death.

Before releasing her from the hospital following a five-day stay, Blackpool and Fylde coroner Alan Wilson concluded that the medics treating her had overlooked the “red flags.”

Before Ryleigh was released, they had lost the chance to investigate her lack of movement in greater detail.

Three months later, she died.

Physicians need to have known that the girl’s declining health might be related to a neuromuscular issue.
