Trial sabotage man jailed for life

A man was finally jailed for life for murdering a grandfather after sabotaging his first trial by soiling himself.

Joseph Tripp stabbed electrician Derek Mcallister in the back with an eight-inch knife after a row in a Coral bookmakers in East Finchley, London, in December 2015.

A trial last year was halted after Tripp, 35, swallowed razors, soiled himself and refused to answer questions about the killing. Following a retrial, he was found guilty of murdering the 55-year-old widower and jailed for life.
