Police issued warrant for paedophile's arrest 18 months before he killed partner's toddler

Police failed to execute an arrest warrant against a paedophile for 18 months before he killed his partner's two-year-old daughter. The victim, Isabelle Welsh, suffered weeks of abuse prior to her death. Despite the warrant being issued months before the murder, authorities did not arrest the abuser. This failure occurred during the period leading up to the killing of the toddler, highlighting a significant lapse in police action regarding the suspect's arrest.
