Doctor outlines gruesome catalogue of injuries
The doctor also outlined a gruesome catalogue of injuries suffered by the 54-yearold.
They included 30 to his head and neck, caused by more than one weapon.
Christopher Graham, 30, of Washington, is on trial at Newcastle Crown Court accused of the murder, which he denies.
The court has heard Mr Bowman was found dead in his flat in High Street, Jarrow, with extensive head and chest injuries, deep stab wounds and some of his digits removed.
Jurors have heard the injuries were inflicted both before and after Mr Bowman died.
Dr Bolton told the court she visited the flat when Mr Bowman's body was still inside.
She added: "Even just looking at it from a distance away, he had very obvious head injuries and very obvious injuries to his face, such that there was a lot of blood around his face.
"We could also see injuries to his arms and his legs, where they weren't covered with clothes.”
The doctor told jurors the injuries to Mr Bowman's face and neck were extensive. She said 26 of the injuries to the face and head were caused through blunt force, which could have involved a weapon such as a hammer.
Four of the injuries, including the gaping injury to his neck, were likely to be caused by something sharp, such as a knife, after his death.
Dr Bolton said the injuries inflicted after death could have been minutes or hours after Mr Bowman stopped breathing.
Jurors have heard Graham had moved into Mr Bowman's flat and was living there of the time of the attack.
The court has heard Graham admits he was solely responsible for Mr Bowman's injuries but maintains his actions were lawful.
The trial continues.
