If you zoom in too quickly, Google Maps may claim that it does not have the needed maps. Zoom back out, wait a few seconds to allow maps to load in the background, and then zoom in again.

If more than one point is mapped for the marked individual, the map also displays chevrons to guide you from the first sighting (shown as a green icon) to each subsequent sighting over time. The chevrons do NOT represent a path of travel, just a sequential link across time.
