A BBC Inside Out investigation has found that a man arrested over the murders of a Northampton family had been sleeping rough in Morocco for over a year.
Jifeng Ding, his wife Helen, and their two daughters 18-year-old Nancy and Alice, 12, were all stabbed to death at their home in April 2011.
Police believe Anxiang Du, who lived in Coventry and ran a Chinese medicine shop in Birmingham, may have committed the murders on the day of the Royal wedding last year.
The programme also reveals Moroccan police arrested Mr Du just five days after the murders in the belief he was an illegal immigrant.
However, he was later released because they could not determine his identity and had no idea he was wanted by police in Britain.
