Two teenagers have been jailed for nine years each for the "brutal" murder of gunman Tristan Sherry, who was beaten to death after he shot and fatally wounded gangland figure Jason Hennessy Snr in a busy restaurant on Christmas Eve two years ago.

Before their trial commenced last year, the High Court found that a law requiring that the pair face a mandatory term of life imprisonment should they be convicted and reach the age of 18 before their sentencing hearing was unconstitutional.
