The team(including Justin: using first name here for convinience's sake) had a trip to Austin. Where they were should be a public knowledge. Perhaps they(you) started the search from there. A facebook search or so could tell some plans of people who would have fun at that particular place. It is also possible that during the few days' correspondence one of the engineer guys had some other piece of info that we are not familiar with. Seeing how the engineers already knew her high school, I'm sure Justin talked about her with co-workers. I think the key information that's missing here is what the engineers knew but Justin didn't know that they knew.(Sounds like a quote out of a Friends episode, mmm)
