What does someone do when you find notebooks like that of James Holmes (movie theatre killer) written by your recent ex husband/childs dad (divorce due to admittance of non heterosexual), and some you can tell were current due to walmart lists i remember giving also noted on some pages?

Should be noted:
Divorce due to admittance of non heterosexual and not ended in a waring but more supportive way.
After the divorce he admitted of being schizophrenic since a teen, all of this was a shock to everyone.

After seeing James Holmes notebooks on the news I realize that i have found about 50 of a similiar type while cleaning out the house, any constructive help would be appreciated.
