I was just watching coverage of this. From what I can gather, it looks like he had engine trouble right after take-off, was trying to return to the runway and just didn't make it back. Not surprising if it happened at take-off, because you are going to have very limited altitude and airspeed to work with. Luckily, the golf course was right there.
When I got my PPL, most of the training was covering various types of engine or flight problems. Losing the engine at take-off is arguably the most dangerous for that type of aircraft because without the engine, it essentially becomes a glider and ny maneuver you do will cost you altitude.
