The man had arrived early in the morning, and was last heard from at 11:04, but had become uncontactable by phone. Concerned associates of the man escalated this to the Police, who in turn requested our help in locating the man.
Our attempts to locate the man's phone using the normal smart-phone process were not delivered, indicating that the man's phone was flat or out of signal. With no location to work from, and no information that there was anything more astray than a flat phone battery, and that the man was intending being out overnight, no further action was taken.
