It is key to have identifying information (documentation, photos, serial numbers, etc) on hand on all machinery that is transported. When machinery is stolen, online (dark-web) marketplaces should be monitored to see if the machinery is offered. If they show up, a certified investigator can make a trial purchase to confirm it is indeed stolen machinery. Always engage law enforcement, and file a police report.
