My cousin has himself and others in serious danger

[irrelevance]

If you spot my posts on other forums, I am trying to get as many varied responses as possible, so trying as many forums as I think might pertain to the issue.

My cousin is almost 19, and has been a rather depressed type of person pretty  much his whole life. His upbringing wasn't great, his parents have a very disagreeable dynamic, and divorced a few years ago, and both are with other people.  His mother has her own domestic issues, and I guess his father probably does too.  My cousin has been almost sort of fending for himself for some time now, he dropped out of school over a year ago.  He receives money from both parents, and it is not the financial aspect he is alone on, but the emotional.  He started to turn more to drugs , I do not know how long ago.. but all I know is that he does many different pills, and drinks.  He has always talked about suicide, joked about it, and just brought it up  more than the average person.  Obviously thinks about it a lot. I guess being the typical 'tortured soul' of a musical artist, most just wrote it off for a while, or didn't know what to do.

NOW, I am hearing for the last couple months he has been saying when he gets mad and throws his little tantrums  (He has developed into sort of a toddler, almost.  spoiled, demanding, self centered, etc.) he tells anyone off, cusses them out etc. at the drop of a hat. And so many of his family members have heard him use suicide as a threat.  Well now he has been saying recently, apparently, that he is going to take as many people as he can when he goes.
This is rather concerning.  Especially on a personal level considering I have been on his 'list' for quite some time now..

Well, just yesterday the family catches wind that he has just bought a hand gun.

There is no reason why we should not take this seriously.  And I am infuriated by the idea of considering I should fear for my own life, at the hands of some "psycho" that is my "cousin".  With the anger aside, I am just here to ask, what can I do?

Is there anything at all I can do?  Is there any institutions (Ohio area) where you can forcibly emit a person on account of being a danger to himself and others?  I know I have no proof of this, and the cops can do nothing.
What do I do?

I don't want to just sit back and wait for the day to come... And I honestly feel as though my life, and those of my family members is truly in danger.

Aquarius-it doesn't matter if someone has a permit for a gun here in the USA....if they want one bad enuf they will get it and use it!TOO MANYguns in the hands of those who shouldn't have them here in the USA!I hope Kstarr and her family members call the police each and every time he threatens them......it will be logged and accumulated.....and it will be up 2 a judge to decide his fate!in Ohio to be taken to a state psychiatric facility against your willl u have to be violent suicidal and threatening others and the police have to be witnessing this...plus a mental health worker has to be called in to pre-screen the person for the admission with a police transport to the facility.

This is a threat you should not take lightly. Please seek more official advice, I fear for your safety, surely there's something you can do. Im assuming he hasnt got a permit for that handgun, or what? Try to find out where he keeps it, and inform the police to do a search. Please dont just do nothing, let me know how you get on, you'll be in my thoughts.

Probating someone in Ohio these days is a nightmare and a thing of the past.....most state institutions have had severe funding cuts and limit who they take and probating someone takes a few months or longer.All u can really do is when he makes threats and u r a witness to call the police and log a report...what they do with it is a entirely different matter!If he gets combative with the police or threatening to them or if he does this to others they will have to take action and press charges against him..then it is up 2 the courts!!!there is NO easy answer to this one!
