Dave Kleiman was to become the most important person in Wright’s professional life, the man he says helped him do Satoshi’s work. They met online: they visited the same cryptography forums and had interacted since 2003. Both men were interested in cyber security, digital forensics and the future of money, but Kleiman was a boy’s boy, an army veteran who loved contact sports and fast living. Five foot ten and weighing 200 pounds, he lived in Riviera Beach, Florida, and from 1986 to 1990 he was an army helicopter technician. When I looked into Kleiman’s life, I discovered he had also done computer forensics work for Homeland Security and the army. After active service he became a deputy in the Palm Beach County sheriff’s office. A motorcycle crash in 1995, when he was 28, left him in a wheelchair. Kleiman was a drug user and one source told me he was heavily into online gambling and various illicit activities; there is evidence he was associated with Silk Road, the online marketplace for all things illegal. After the accident he devoted himself to computers, and set up a company called Computer Forensics LLC.
