In September of 1992, three different groups arrived. Who were they?

Group One:

Thompson, Samel, and Swanson, however, are contumacious Alaskans with a special fondness for driving motor vehicles where motor vehicles aren’t really designed to be driven.

Group Two:

When they got there, according to Thompson, they found “a guy and a girl from Anchorage standing fifty feet away, looking kinda spooked.”

Group Three:

At eight-thirty the next morning, a police helicopter touched down noisily beside the bus in a blizzard of dust and swirling aspen leaves. The troopers made a cursory examination of the vehicle and its environs for signs of foul play and then departed.
