Mark Nash has pleaded not guilty to murdering two women at the Central Criminal Court, where a retraction letter was read on 20 February 2015.

The charges concern Sylvia Shields and Mary Callanan, who were killed in Grangegorman between 6 and 7 March 1997.

The letter withdrew Nash’s earlier statement claiming responsibility and attributed his knowledge of the killings to media reports and other accounts.

The trial continued after the jury heard evidence about Nash’s statement, sketches of the house and the circumstances surrounding his account.
