Contact the authorities in IN in the town he is visiting and let them know that he has your 5 year old and has threatened suicide. He sounds like a cowardly sociopath that "probably" won't hurt himself but just in case, you want to demonstrate responsible behavior with regard to your daughter.
My STBXH used to do similar things as your H. After 5 years of separation, our D will be final in two days. He now tells me that he just thought I would always be there for him, no matter how sh!tty he was to me. It is JUST NOW hitting him that I am done!
Best of luck.
