Some interesting bits from the report:
Yun did not go gentle into that good night; he was a black belt martial artist and fought back so hard that he broke bones in his hands.
There was a track of bloody sockprints that led straight to where Yun kept a large amount of cash hidden in his house.
One of the weapons used in the attack on Yun left an odd pattern of vertical striped bruises, and there were also T-shaped puncture wounds on the body, which may have been caused by the same weapon.
