A criminology student who stabbed a personal trainer to death on Bournemouth beach has been jailed for 39 years.
Nasen Saadi, 21, fatally stabbed 34-year-old physical trainer Amie Gray and injured her friend Leanne Miles as the pair enjoyed a late-night chat at the Dorset seaside resort on May 24 last year.
The defendant, who had been studying at the University of Greenwich, had collected knives and researched locations to carry out the killing - and had even asked his course lecturers questions on how to get away with murder.
He was also sentenced at Winchester Crown Court for failing to give his mobile phone pin code to police.
Armed with a knife, Saadi approached Amie and Leanne, 38, as they were sat on Durley Chine beach shortly after 11.30pm.
Without warning, Saadi attacked Ms Miles by stabbing her more than a dozen times. Ms Gray bravely distracted Saadi by shouting at him to 'get away' from her friend, allowing Ms Miles to flee.
Ms Gray was stabbed 10 times and would not survive her injuries.
