"Why, Lord?", a tragedy today

I just saw this news, and I think it puts many things into perspective for anyone struggling in ways that greatly pale in comparison to this. Steven Curtis Chapman is a great musician, but I am even more grateful for the work he and his wife have done for adoption in this country. They are an amazing family that I have long admired, and this tragedy that struck them today is one of those times we find ourselves asking "why, Lord?". Please pray for the Chapman family!! God knows the plans He has for us, His mercies are new every morning, and He works all things together for the good. Let's trust Him, even in tragedy!
In case you haven't heard this news, here it is:

NASHVILLE, Tenn. (AP) — The 5-year-old daughter of Grammy-winning Christian music star Steven Curtis Chapman was struck and killed Wednesday by a sport utility vehicle driven by her brother, authorities said.
The girl, Maria, was hit in the driveway of the family's home Wednesday afternoon by a Toyota Land Cruiser driven by her teenage brother, said Laura McPherson, a spokeswoman for the Tennessee Highway Patrol.
The brother, whose name and exact age weren't available, apparently did not see the girl, McPherson said. No charges are expected.
"It looks like a tragic accident," she said.
Several family members witnessed the accident, which happened in Williamson County just south of Nashville. The girl died later at Vanderbilt University Medical Center in Nashville, hospital spokeswoman Laurie Holloway said.
