Nearly a year after chef Xiu Bin Wang, 33, was found dead in his room above China Chef carryout restaurant in Brockenhurst, Hampshire, England, police are still trying to figure out how he died, Metro News reported. 

Chef Wang apparently suffered a “forceful blow” to the head, and officials first fingered Zhu Long Guo, a colleague at the restaurant who admitted to striking Wang with a ladle during an altercation. “A ladle was seized, and there was a thorough investigation,” Detective Constable Brad Wanless reported at an inquest in July. 

But the coroner could not make a definite determination, and issued the following statement: “I do not accept that there is a clear causal link between the admitted blow with the ladle and the death of Mr. Wang,” senior coroner Grahame Short concluded.
