What advice do you have on handling a suicidal soldier, after multiple approaches have already been tried?

So, this is a little bit of a long story so ill try to shorten it: A soldier i recently took responsibility for (Was given after an APFT and height/weight failure) has had issues with disrespect towards junior and senior NCOs, has been late for work almost everyday, has had multiple FTRs for assigned duties, etc... almost everything you can name a bad soldier does he has done it. Since taking over as his first line and NCO, i have counseled him on all of this. I gave him verbals the first offense, then put it on paper and it actually got his attention. After this last counseling he got upset and started yelling and essentially told me he wants to kill himself, and not only that but he wants to do it in front of senior leadership so they can see how bad he is hurting. I reported it up the chain, he was on suicide watch until BH facilities were open then admitted to the hospital. He spent the weekend being evaluated and was released. After release and return to work, he jumped the chain of command and asked that i not be his supervisor, although i am still my shifts NCOIC and he is on my shift. They agreed and now we are in a situation where he does not reply to my text messages or phone calls, and he goes on leave for 30 days so i will not see him until he returns. My question is what else can be done with this soldier? I have already suggested he be moved, and that all of his weapons be removed from his home, (which was not done) and he blames not only the unit but the leadership for his behavior and actions. I guess i'm just looking for advise or a "what would you do in my situation"?
