I don't know enough about the specific case of Wesley but have heard others talk about it.
In my experience at work, we have sniffed out several people who greatly embellished on their resume over the year, but I'm sure that even more people got stuff by us without us having the information to verify.
Two instances I can best remember were:
1) Representing Harvard Extension School as Harvard University and speaking about it as if they had been accepted to the university
2) Person who had done an internship delivering coffees to the local news station wrote "Emmy Award Winner" on her resume because that news station ended up winning a local news emmy award
