Nasen Saadi, a criminology student, is on trial for the murder of Amie Gray, 34, and the attempted murder of Leanne Miles at Bournemouth beach. Saadi allegedly asked questions about getting away with murder during his studies and researched beaches and weapons before the attack. Witnesses reported hearing screams as the incident unfolded, with Saadi captured on CCTV days prior. Although he denies the murder charges, he has admitted to hindering the police investigation by not providing access to his mobile phone. The trial continues.
