I think it may well be a fan blade.
The dovetail root length from the very useful GA is about half the span of the fan OGV, and the leading edge of the fan blade is about one OGV span from root to change of curvature in profile. Also , the root is the correct colour.
And a bit of containment on the blade tip.
Fan failures are very chaotic affairs and we cannot possibly predict the sequence of events from the limited material available.
I'm sure East Hartford will have a very good idea by now.
