The jury has retired to consider its verdict for a second day in the trial of a Croydon student accused of the murder of physical trainer Amie Gray on Bournemouth beach. Nasen Saadi, 20, denies murdering Aime and the attempted murder of Leanne Miles.

Winchester Crown Court was told the women were attacked as they sat chatting at Durley Chine Beach, West Undercliff Promenade, late in the evening of May 24. The jury has seen CCTV footage of a man walking along the seafront before attacking the pair.

Saadi, who was studying criminology and criminal psychology at Greenwich University, has admitted to staying in Bournemouth at the time of the attack but has denied being the person shown on the CCTV.

He told police that he could not remember that period of time and said he might have “blacked out”, that his arrest had been a case of “mistaken identity” and he had “no reason to attack someone for no reason”.

During the trial, the jury also heard Saadi was interested in true crime, horror movies and knives which he bought on the internet and had called himself “Ninja killer” for his username on Snapchat.

Home Office pathologist Dr Basil Purdue told the court Amie died as a result of 10 knife wounds including one to the heart while Leanne suffered 20 knife injuries.

The court also heard Saadi admitted failing to provide his mobile phone pin code to police.
