If you look at the kml file in Google earth, her approach was spot on the first time and she went missed at approximately 4375 msl.
Appears to be procedure on missed and second approach was virtually identical to the first except the last 3 pings were a touch lower than the first approach.
(The last ping was on the ground so you can’t count that as part of the glidepath)
A deeper comparison shows the rate of descent continues at a higher rate on the second approach.
First approach from 6125-4375’, vertical drops were 1000,1000,975,913,128. (I assume this is vertical difference between pings)
Second approach at roughly same point is 643, 984, 946, 663, 750, 857. I would disregard the last one as invalid, but you can see the trend of continuing down without change.
Weather was 2.5 in snow. Perhaps she broke out from the ovc and went visual. Hard to know.
Without intimate knowledge one theory might be she contacted one of the towers, silos, or wires in the flight path. Structures are very evident in Google earth leading up to the final location.
