I just came online to post this and Blonde beat me to it. It may have to do with the the possibility that the investors were Chinese looking for a path to US citizenship by investing at least $1m and creating at least 10 jobs each under EB5 to get a green card. They may have gotten what they wanted and pulled out or may have never been concerned about the company's success or failure in the first place. Of course, no one is saying much. The casino hotel stated that they plan to reopen in about six months and will offer laid off employees their jobs back at that time. Of course, I would expect most to have found new employment by then and given the property's track record, it may not get the investors it needs to reopen.
