摘要： A person tracking support device includes a processor. The processor acquires identification information of a tracked person identified from a face image of a person imaged by a first camera, and a first time at which the tracked person is imaged by the first camera, and also acquires a second time at which the tracked person is imaged by a second camera positioned away from the first camera, predicts a time at which the tracked person reaches a specific area on the basis of an elapsed time from the first time to the second time and a distance from the first camera to the second camera, and notifies a mobile terminal device possessed by each of a plurality of observers of the identification information of the tracked person, the specific area, and the time predicted.
