The flight was in the air for about 14 minutes and had reached an altitude of just over 19,000 when radar noticed the plane was in a descending right turn at a high rate of descent, Landsberg said.
Obviously no idea what happened, but sounds like they went into a dive that exceeded the airframes survivable speed.

Weren't there reports of extreme turbulence in the area?? I know there's a certain YouTuber out there talking about spatial disorientation but I think this is leaning more to the plane just falling out of the sky due to something failing mechanically. They found the tail horizontal stabilizer about 3/4 of a mile from the airplane along with part of the right wing.
Edit*
If you look at the flight data, he was flying straight and climbing before the right hand turn into the dive. It seemed to me that a mechanical issue might have caused loss of control which then caused additional breakage aka that right wing tip. There is a weird right turn left. Turn correction but at that point he starts climbing for quite a distance before the issue seems to happen. Therefore, leading me to believe that it wasn't necessarily spatial disorientation but mechanical failure. I'm no way educated to make this guess.

Likely a mid air collision with an object, strong likelihood it was a large bird. I worked for a different medical aviation company and they had a similar type of wreck with a bird collision. Bird crashed through a windshield on the pilot's side killing the pilot or disabling him, and the whole thing crashed. There may be a news article somewhere to dig up. I can't remember exactly where it happened though, somewhere in the northern midwest of the US.

Likely? At 19,000 feet you’re not running many birds and during a winter storm you’ll see even fewer.

It's possible a bird might have struck the tail horizontal stabilizer. That piece along with the tip of the right wing was missing from the wreckage (by 1/2-3/4 mile) implying that it came off prior to the aircraft hitting the ground.

Jesus.
Don't speculate with no real data to work with.
Have some decency.

I'm hoping (relatively speaking) that it was catastrophic failure and not suicide.
The fact that radar showed it in a turn kind of makes me think it was mechanical. I'd assume with suicide you would just point the nose straight down or fly into a mountain.
Don't know what, if anything, was said over the radio but the turn may have even been started as an attempt to turn back when they realized something was wrong.

Could have been icing on the wing. Pilot tried to correct unsuccessful. I used to fly as a medical crew in the PC12 and it’s a tough aircraft, but icing was always a concern.

Icing should be pretty easily detectable in the PC-12, though, and I'm not sure Pilatus even sells any of them without ice control systems. Not to say it couldn't be a factor, but the pilots are trained and the planes are built to deal with it, and they tend to fly in icing conditions a lot.

I’m a former aviation meteorologist, and icing was my first thought. It would cause a nose-up AOA and eventual stall. Looking at the obs, there was a ceiling at 060 with light snow. Temps at the surface hovering around freezing. You can get a fast accumulation of clear ice in those conditions. You can also get induction freezing in the engines when they are revved up for climbing.
Combine a frozen engine, clear ice, and a sudden stall and spin, and it wouldn’t take much for something to break off.

Blancolirio has a hypothesis about going off autopilot (for which there are many possible reasons) and spatial disorientation (which happens a lot when one is hand-flying in extreme IMC).
Of course we're all waiting for the actual investigation.
