Keith Cormican has a very unusual job: he finds and retrieves dead bodies in lakes and rivers across the country. Cormican has been especially successful in Lake Tahoe, where in just under 2 months in 2017, he found six missing bodies — some of which had been lost for more than 10 years. Chronicle lifestyle and outdoors editor Gregory Thomas tells the story of how Cormican became an expert at finding dead bodies and how he pulled off the deepest body recovery on record in North America. | Unlimited Chronicle access: sfchronicle.com/pod  Learn more about your ad choices.
