Dad emotional to learn drug site shut down THE father of a Perth teenager, who died after falling from a balcony while on drugs, says he is "over the moon" knowing the website that sold them has been shut down and its alleged mastermind arrested. Preston Bridge died in February when he fell from a balcony at the Sunmoon Resort in Scarborough following an after-ball party. The 16-year-old was under the influence of drugs, possibly a hallucinogen, bought by a friend from the Silk Road website. His father, Rod, has been campaigning to close down the website since his son's death. He sounded emotional while giving an interview on Thursday after learning the alleged mastermind of the website had been charged and the site closed down. I'm over the moon ... It's been a terrible six or seven months, but the news this morning was overwhelming," he told Fairfax radio. Mr Bridge said he felt closure and hoped the arrest would deter others from committing such crimes. "It will most probably save a lot of lives and get these people locked up and put away," he said. The 29-year-old alleged architect of Silk Road, Ross William Ulbricht, who went by the alias Dread Pirate Roberts - a reference to the 1987 film The Princess Bride - was caught at a library in San Francisco on Wednesday. Over the past two years, the website became a black market bazaar that allegedly brokered more than $US1 billion ($A1.07 billion) in transactions for illegal drugs and services. Users of Silk Road could anonymously browse through almost 13,000 listings under categories like "psychedelics" and "stimulants" and make purchases using the electronic currency Bitcoin. The website protected users with an encryption technique called onion routing which makes it almost impossible to physically locate computers hosting or accessing websites on the network. Ulbricht has been charged with a raft of offences including computer hacking conspiracy, narcotics trafficking conspiracy and money laundering conspiracy. Mr Bridge said he hoped a coroner's hearing into his son's death would be held next year.
