Eyewitness reports are notoriously inaccurate and virtually all sound the same regardless of type of aircraft or actual circumstances: "spiraling (or spinning) out of control", "stalling", "on fire", "diving".
In this case I might actually believe the spinning part if he snapped the fenestron driveshaft after slowing down to set up his approach to the hospital and was unable to stop the spin with power decrease and airspeed increase and quickly committed to the autorotation. At that point he would not have been spinning anymore, though.
In this case we may actually get to find out what happened since everyone lived and the aircraft is relatively intact.
It's looking like he did a pretty good job. Nobody seriously hurt, aircraft is upright, no persons or property at the landing sight adversely affected.
