AN 18-YEAR-OLD found buried beneath a shed may have been incapacitated by a hammer blow to his head before he was stabbed in the neck, the Old Bailey heard today.

The body of Stephen Ojerinola was found encased in concrete last November, buried in the garden of 5 Lynsted Gardens, Eltham, where one of his alleged killers William Regan lived.

Forensic pathologist Dr Peter Jerreat told the court there was a large mass of concrete inside the teenager's hooded top which he had to chisel away before a post-mortem examination could begin.

Despite the condition of the body, Dr Jerreat identified a depressed fracture of the skull, along with an 8cm stab wound to the chest and a number of stab wounds to the neck.

He said the chest wound was "capable of causing death on it's own" while the neck injuries were likely to have been inflicted while Mr Ojerinola was "relatively still".

The court heard the head injury was likely to have come from a hammer.

The pathologist said: "What I can say is that the neck wounds are likely to be the last wounds because he's lying still so they either followed the head wound or they followed the head wound and chest wound."

Regan, aged 36, and Lee Davies, aged 36, of Chiswell Square, Blackheath, both deny murder.

The trial continues.
