Ren S'orn
From Wookieepedia, the Star Wars wiki.
Ren S'orn was the son of Senator Uta S'orn. He was Force sensitive and was identified at a young age for Jedi training. Senator S'orn, not wanting to part with her son refused to allow him to go and train within the Jedi Temple.
With the knowledge that he could have become a powerful Jedi, Ren S'orn was unable to cope with the premonitions and telepathic struggles that he was unprepared for. Becoming moody and depressed, he eventually abandoned his mother and was captured by Jenna Zan Arbor who ran tests on him. Eventually he was killed on Simpla-12, where he was found drained of blood.
