Emma Caldwell killer's past

Stuart Hall, a former detective constable, believes that Packer's prolific history as a sex offender points to 'more tragedy' that has yet to be uncovered.

Packer was convicted of Caldwell's murder nearly two decades after the event, following a long campaign for justice by her family and investigative journalists.

The new allegations suggest that police may have overlooked critical evidence in other unsolved cases involving vulnerable women in the Glasgow area.

Families of other missing women are now calling for a full review of Packer's movements and potential links to cold cases dating back to the 1990s.
