Murderer Timothy Caines, who is serving a life sentence for the killing of a Birmingham lawyer, is to have his case reviewed for the third time.

Caines, a former financial adviser from Birmingham, was jailed for life for repeatedly stabbing Colin Hickman, a Moseley lawyer, in March 1994.

Mr Hickman, who was aged 55, was attacked as he opened the door of his home in Earlsdon, Coventry.

The Criminal Cases Review Commission, which investigates alleged miscarriages of justice, is to study the case after Caines' solicitors raised fresh doubts about his conviction. The case could now go to the Court of Appeal.

The Birmingham city centre-based CCRC examined the possibility of injustice to Caines when it reviewed the case in 1997 and 2003.

Caines admitted he had been near the murder scene when detectives found his baseball cap and watch by Mr Hickman's home. But the inmate of Leyhill Prison has protested his innocence .
