Abstract: Systems and methods to request and collect evidence elements from one or more evidence systems responsive to a triggering event are disclosed. An evidence request beacon may be generated based at least in part on information associated with the triggering event. The evidence request beacon may be received by one or more evidence systems and may be evaluated to determine if potentially relevant evidence is available from the evidence system. If potentially relevant evidence elements are available from the one or more evidence systems, then the potentially relevant evidence elements may be provided to the requesting system.
