Convicted killer Joanna Dennehy was caught on CCTV just minutes before she attempted to murder two men in Hereford.

Jurors in the trial of Dennehy's boyfriend Gary "Stretch" Richards were shown the video at Cambridge Crown Court where he denies three charges of preventing the lawful burial of three men killed by Dennehy, in Cambridgeshire.
