Mrs Ellman said: "Setting up this organisation is hugely to his credit and will hopefully teach others in a similar position about ways to live again and boost them as individuals.
"John has had to be a fighter as psychologically it's been a very traumatic experience for him."
Freed after 19 years of hell
JOHN Kamara was found guilty of knifing to death betting office manager John Suffield in 1981.
A court heard the he fled with £176 cash, leaving Mr Suffield, 23, dying in the Coral bookmakers in Lodge Lane, Toxteth, from 19 stab wounds.
Mr Kamara always maintained his innocence but a Home Office inquiry led by Merseyside police between 1987 and 1992 found no evidence for appeal.
The case was taken up by Channel 4's Trial and Error programme in 1997.
The criminal cases review commission said there were possible doubts over the conviction and it was referred back to the court of appeal.
In March, 2000, judges at the court of appeal ruled Mr Kamara should be released after hearing 201 documents had not been disclosed to his defence team during his trial for the murder of Mr Suffield.
Raymond Gilbert, 47, was jailed for 25 years for murder for his part in the death, and remains in prison.
He is asking the Criminal Cases Review Commission (CCRC) to review his case.
