I'm not sure how much of this I should belive since sources in kpop/cpop are either overtly sympathetic or overtly vicious when it comes to relaying an incident or information, there's no neutral news source in the beginning stages.
The allkpop article gives a good overview of what happened till a day or so ago
A Twitter account kris wu vs dmz is giving updates which has actual links of the posts and recordings the friends are making....there's more on their page..Heres their latest update....
From the name itself please be wary of what you read unless it comes with the link, since it won't be unbiased.
I'll refrain from posting a summary of what I think because I'm careless with my words and even small mistranslations can have huge implications and I'm not sure what to believe at this point. Whether it's true or false it's truly a tragedy.
