IIUC from those two articles, first there was a US police investigation into Lucy Harrison's death looking at possible manslaighter by her father, Kris Harrison.
Then a grand jury session was held in Collin County, Texas, USA where the grand jury "determined there was insufficient evidence to charge anyone in connection with Lucy Harrison's death."
Now there has been an inquest in Warrington, in the UK, where Lucy Harrison lived. The British coroner has found "Lucy Harrison died due to unlawful killing on the grounds of gross negligence manslaughter."
Both Kris Harrison and Lucy's mother Jane Coates had legal representatives at the Warrington inquest. Kris' lawyer tried to get the British coroner to recuse herself, claiming possible appearance of bias (no mention in the article of what this might be), but coroner refused to recuse.
