A school teacher described Martin Treacy as a young man with a 'polite nature', who was 'respectful, thoughtful and quiet'. A neighbour of Treacy's said the 18-year-old was 'well mannered', and would go out of his way to help others.
"I have never seen a bad side to Martin," she said. One person who saw Treacy's terrifying bad side was Uber driver Ali Asghar. Mr Asghar was beaten to death as he tried to make an honest living to support his family.
Also in Mr Asghar's Mercedes that night was Treacy's pal, 20-year-old Connor McPartland. The pair had known each other for nearly a decade, playing football in the park together as youngsters.
