I had a client threaten to kill me. It was pretty crazy. Turned out he had two identities and gave me an Israeli passport under an assumed name to hide the fact that he had done time for money laundering for Colombian drug cartels. He gave me a whole bunch of forged documents and tried to collect on a judgment he wasn't entitled to. I figured it out after I already had the money and I gave it to the people who were actually entitled to it. They were very grateful. He was convinced I owed him $200k and made it very clear he was going to sic the cartels on me. I went into hiding for awhile. Not a great experience.
