A criminology student has been found guilty of manslaughter and attempted murder after stabbing two women on Bournemouth beach.
Amy Gray, 34, was killed and Leanne Miles, 38, was seriously injured in the attack on Durley Chine Beach on May 24.
Nisin Saadi, 20, from Croydon, was found guilty following a trial at Winchester Crown Court, and admitted failing to give police access to his mobile phone.
Prosecutors said Saadi “seemed to want to know what it would be like to get killed”.
The jury deliberated for 5 hours and 36 minutes and reached a verdict after a 9-day trial.
Judge Mrs Justice Cutts told Sadie: “You have been sentenced for the most serious offences.”
It added that he faces life in prison, with a minimum term of “substantial length”.
Saadi will be sentenced at Winchester Crown Court on March 28.
On the night of the attack, the two women were sitting on the sand where they had lit a fire.
Jurors were shown CCTV footage of Saadi walking along the promenade before stepping on the sand and attacking the couple, leaving them bleeding.
Ms Gray, a fitness instructor, was pronounced dead at the scene after paramedics arrived.
Ms Miles was taken to hospital with 20 stab wounds, mainly to her back.
Saadi, who was studying criminology at the University of Greenwich, was arrested on May 28 at his aunt’s house in Purley.
Police found a number of knives and self-defense spray in a bedroom at the property.
During the investigation, no weapon or clothing was recovered from the night of the murder.
In a police interview, Mr Saadi told detectives he was interested in unsolved crimes, such as the Setagaya family murders in Japan.
Saadi refused to reveal his passwords, and admitted to failing to give police access to his mobile phone.
The jury was told that on his laptop, investigators searched the internet for “the deadliest knife”, “Why is it so hard to catch a criminal if he does it in another city” and “Which hotels in the UK have CCTV?” Information about V is not found. .
He also saw “Bournemouth CCTV” and “Bournemouth Pier CCTV” in the days before the murder.
The jury was shown CCTV footage which Ms Jones said captured Saadi traveling from Croydon to the Travelodge Hotel in Bournemouth on May 21.
He surveyed the area before going to the Silver Haw Hotel on 23 May.
In the footage shown in court, detectives asked Sadie what she did after checking out of the Travelodge on May 23.
Saadi said “I don’t remember, maybe sleepwalking… I probably blacked out” and told detectives his next memory was at home on May 25.
He told investigators he was a victim of “mistaken identity” and said “it’s not me” after being shown CCTV footage from the night of the attack.
Sadie chose not to give evidence from the witness box, and Mr Sherrard, defending, gave no further evidence.
