A criminology student spent a month planning a random killing spree before stabbing two women to death on a beach at night, a court has heard.
Winchester Crown Court was told that Nisin Saadi killed Amy Gray, 34, and seriously injured Leanne Miles, 38, on Durley Chine Beach in Bournemouth on May 24.
Sarah Jones, QC, prosecuting, told the jury: “It seems he wanted to know what it would be like to get killed.”
Mr Saadi, 20, from Croydon, denies murder and attempted murder.
Ms Jones said the defendant began selecting a site for the attack in April, researching beaches in the south of England and settling on Bournemouth.
On the night of the stabbing, the two women were sitting on the sand where they lit a fire and watched the full moon, the barrister said.
He continued: “With purpose, slowly, stealthily and quietly; when he thought no one would observe him, he hovered over the edges of the walk, then stepped onto the sand.
“In his act of brutality and randomness he stabbed them both multiple times, chasing them as they tried to escape or push him away from the other and he continued his attack.
“He left them on the sand to bleed as he walked away and tried to disappear back into the shadows, away from the glare of streetlights or moonlight and back into anonymity.”
Miss Gray, the pool’s soccer coach, was pronounced dead at the scene. Ms Miles was taken to hospital for treatment of stab wounds to her chest and back.
The prosecutor said the defendant, who had researched whether people would be on the beach and “hotels without CCTV”, may have wanted to feel powerful or intimidate women.
Ms Jones continued: “Maybe he couldn’t bear to see people engaged in happy normal social interaction and decided to kill the butcher, to hurt him.”
The court heard Mr Saadi asked a Greenwich University lecturer in 2023 to defend himself about the murder and DNA evidence.
The lecturer replied: “You’re not planning a murder, are you?”, the jury was told.
The jury was told the defendant had admitted refusing to give police access to his mobile phone.
The trial is ongoing.
