I saw on Facebook that she passed away, such a sad loss for the barrel racing world.  Does anyone know what happened to her? 

Yes saw that too. Don't know what happened. What a loss!

I got to see her in the flesh years and years ago when she was young and the Dunns were still in MO. Man was she magnificent. What a loss. 

prayers to the Dunn family,and to Troy and Renee.Such a huge loss:((

I went to their Facebook and saw the loss of this family has in losing this mare, sending them prayers, so sad to read that they have broken hearts..

Didnt see as to why this happen Im sure somebody will say what happen as the shock wears off after their loss..

Bless their hearts.   She was something else. . . . 

Colic.

I got told from Matt that she had a tumor then colic symptoms and complications.

She was a great one that will be missed. Her legacy will be continued through her offspring. So glad Troy and Titan did so well in memory of her at the BFA. 

Devastating!!!

So terrible! She was a good one!
