The fire brigade in the Lower Saxony district of Northeim found a helpless 83-year-old with dementia with the help of a drone with a thermal imaging camera.

The 83-year-old left a care facility in Bad Gandersheim on Friday afternoon and an employee at the facility reported him missing, the police said on Saturday. A search in the vicinity was initially unsuccessful. In cooperation with numerous firefighters, an extensive rescue operation then took place.

In the meantime, the missing person had contacted a relative via video call, the police said. He told the police that the senior was lying in front of a garden fence. Thanks to the drone with a thermal imaging function, the 83-year-old was found in a helpless position in the evening, but safe.
