Ummm what news are you guys reading? From what I'm reading they issued a distress cloud and were possibly flying in IFR conditions and broke out of the clouds near the building.

The real question should be why he didn't pop his shute?

“I just saw something come across the sky and crash into that building,” she said. Cha said there appeared to be smoke coming from behind the aircraft, and “it looked like it was flying erratically for the short time that I saw it.”

If it was suicide it would have been a strait in.
