My fiancé dated a gang member a long time ago. A friend of hers went to him and put him in the hospital when he found out he raped her all those years ago. He then proceeded to ask my fiancé to sleep with him and she told his current girlfriend who then left him for his disloyalty. Now the gang member is out of the hospital and text messaged me saying I was the one who told them to put him in the hospital, and I am willing to bet its because my fiancé caused a rift in her ex friends relationship. I told him about this and he told me that if he finds out I am lying, he will come after my fiancé and she will never be found. What do I do?

Move away from that city and stop hanging around gang members.

If you know gang people, and hang with them and are invovled with them, this is what happens.
