KAREN Chandler's younger son, Kevin, said his family are still considering bringing a private prosecution against Bryan Maloney.
Mr Chandler, 21, who lives in West Lavington, said he would like to see a change in the law which would see people who have been charged with an offence to be charged again with the same offence.
The law at the moment does not allow this but there has been lobbying recently to change it, particularly in relation to the suspects in the Stephen Lawrence murder inquiry.
Mr Chandler who had sat through the two-week trial at Bristol Crown Court, was outraged when the jury returned a verdict of not guilty.
He praised the police for the way they handled the inquiry and said: "They did their job correctly as far as I am concerned."
He expressed his anger at the verdict and claimed the family had been cheated. He vowed to get justice for his mother.
Mr Chandler had left the court building to go with his brother to a doctor's appointment when the jury returned. He was told of the verdict by a police liason officer.
"I could not believe it," he said.
After the trial he spoke about his memories of his mother.
"I miss mum and think about her all the time," he said.
"She was such a genuine person and was one of the best people I have ever known.
"She was a good laugh. She had the same sense of humour as me."
He said: "She was totally unselfish and she always helped people out. She enjoyed her job and meeting people."
His mother had worked part-time for the Snook farming family in Urchfont before becoming a security guard.
Before her death she was working for the MOD at Lugershall.
A police spokesman said: "The review of the investigation into the death of Karen Chandler is still being undertaken and it is too early to make any kind of comment on it."
Meanwhile, Mr Maloney has been informed that he has no grounds for a law suit for wrongful imprisonment.
He is however, looking into a claim against Wiltshire Constabulary for loss of earnings.
