How police caught killer criminology student without DNA evidence
Criminology student Nasen Saadi has been jailed for life with a minimum of 39 years for the murder of Amie Gray and the attempted murder of Leanne Miles on a Dorset beach.
The BBC explores how police put him behind bars despite having no DNA evidence.
It was a Friday night and the beach in Bournemouth was illuminated by a Blood Moon.
Amateur photographer Mick Priddle was standing on a cliff marvelling at the sky when he heard two loud screams from the sand below.
He was about to become the key witness in a murder investigation.
