That article is the weirdest thing. And what a strange accident -- does anyone know enough about planes to hazard a guess as to what might have happened? To my uneducated eye, it looked like suicide -- deliberate.

Found my answer on youtube comment:

To all those calling into question the age of the aircraft, any brand new twin engine airplane can have the same thing happen. It's called a Vmc (velocity, minimum controllable) roll. If you have an engine failure and the airspeed is below Vmc, the plane will not be controllable. Unfortunate pilot errors... first, letting the plane get that slow; once the roll started the only save is to cut the working engine and regain control.
