Lying teen reinvented himself as an oligarch’s son — and ended up dead in front of intelligence HQ

Worry turned to fear, then panic. Their teenage son was missing. 

Matthew and Rachelle Brettler, a cultured and comfortable Jewish couple living in a respectable London district, watched in confusion as the youngest of their two sons, Zac, changed.

At 19 years old, he was dressing and behaving so unlike the intelligent, entertaining and sociable kid they adored. He had become bratty, a show-off obsessed with imitating an Instagram-polished luxury lifestyle. His idols had morphed from sports stars to Vladimir Putin and “Wolf of Wall Street” crook Jordan Belfort. His outbursts had turned violent and his new friends were nothing like his family: flashy, foreign and inexplicably rich.
