What a terrible accident... very sad.
I really hope it's not seen as insensitive to raise this, but on the surface it appears alarmingly similar to the B200 accident a couple of years ago at Wichita/ICT:
During the initial climb, the pilot declared an emergency and stated that the airplane "lost the left engine." The airplane climbed to about 120 ft above ground level, and witnesses reported seeing it in a left turn with the landing gear extended. The airplane continued turning left and descended into a building on the airfield. A postimpact fired ensued
