So whatever raw data they had available, and in theory were supposed to be monitoring, meant nothing.
If so that was grossly inexcusable. This was not an RNAV IAP. They had no need to use RMIs. They had just passed the IAF (ULQ) and when confusion ensued, a switch to raw data VOR/DME and selecting the 202 Radial would have been all they needed to do. There was no need to use RMIs or do fix positioning.
This is the VOR/DME chart they were using:
