We are live on the ground in Ferguson, Missouri, with the latest news and analysis.
(CNN) - Malaysian officials say they can tell you how Flight 370 ended. It crashed into the Indian Ocean, they'll say, citing complicated math as proof.
They can tell you when it probably happened - on March 8, sometime between 8:11 and 9:15 a.m. (7:11 to 8:15 p.m. ET), handing you a sheet with extraordinarily technical details about satellite communications technology.
What they still can't tell you is why, or precisely where, or show you a piece of the wreckage.
All those uncertainties are too much for relatives of the 239 people aboard the plane, some of whom marched to the Malaysian Embassy in Beijing to denounce the airline, the country and just about everything involved with an investigation that has transfixed the world and vexed experts.
