Bible John

With no solid leads in sight, police stepped up the investigation.

In an attempt to jog the public's memory, a policewoman who closely resembled the dead woman dressed in similar clothing and retraced Jemima's last known steps. This yielded a few additional clues, but still did not lead police to a particular suspect.

Barrowland sign

A rough sketch of the man seen leaving Barrowland with Jemima was created and, for the first time in a Scottish murder investigation, police released the sketch to the media (drawings of suspects had traditionally been distributed solely within the police organization).

Before the investigation had a chance to cool down, another murder gave police the solid lead they needed: a living witness who had shared a taxi with both the killer and his next victim.
