The Ravens' statement says it as well as I could.
"We cannot imagine the heartbreak and sorrow Todd and Ashley's family feels right now. This is knee-buckling news and an overwhelmingly sad tragedy. Our prayers, our thoughts and our hearts are with the Heaps, who have contributed so much to the Ravens and Baltimore community. We believe their deep faith and tremendous support from friends and family will help them through this unimaginable time."
...and the Cardinals.
"Our hearts go out to Todd, Ashley and the Heap family. It is a grief that is beyond words and one which no family should ever experience. Hopefully the prayers, love and support of their incredible group of friends and family provide them comfort that along with their strong faith will lead them through this unspeakably difficult time."
My little girl is nearing 4. I have no idea how I would cope with this.
