A schizophrenic today admitted the attempted murder of his grandmother and her sister in an attack just months after his release from prison.

Lincoln Payne, 29, left his grandmother, Maureen Burchett, 78, in a serious condition in hospital with three knife wounds to her neck and head after the assault in Faversham.

She also suffered several broken bones, multiple cuts and bruises and her front teeth were knocked out.

Her sister Lily McBride, 75, needed a five-hour operation after being stabbed in the stomach.

Both sisters are believed to have lain injured for 24 hours in the home they shared in Fostall Road.

Today, Payne, dressed in a blue blazer and white shirt, pleaded guilty to two counts of attempted murder at Inner London Crown Court.

The court heard Payne, previously of Sittingbourne, is currently being treated at Broadmoor hospital by forensic consultant psychiatrist Dr Samrat Sengupta.

The hearing was adjourned until Thursday to fix a date for a sentencing hearing, which will only take place once medical reports are prepared.

In the aftermath of the stabbing on June 27, a neighbour described the moment she discovered Mrs Burchett with knife wounds on her doorstep while her sister lay injured next door.

Teresa Fergusson, 52, was the first to call 999 after the two sisters in their 70s were seriously injured.

Teresa said it is a “miracle” they survived the savage attack.

Teresa, a coastguard, said: “I had a knock on the door on Sunday afternoon about 4.15pm.

“I didn’t really think anything of it until I opened the door to see Lily stooped over her walking stick, saying ‘help me’.

“I found Maureen on the floor of her house, lying unconscious but breathing.

“There was blood everywhere. It was carnage.

“Her eyes and face were so swollen, she was almost unrecognisable.

“My husband sat with her until the ambulance arrived.

“I went straight back to see Lily. She could hardly speak or move, but mumbled what had happened, saying their attacker had grabbed her handbag and gone berserk. I was trying to keep her awake because I thought she might pass out.

“It was then when she said her stomach hurt and I saw the stab wound and called 999 again to call for an air ambulance.

“They had been left for dead. It’s amazing they are still alive.”
