What happened to Grace Walden Stephens?

What if I told you that the most credible major witness in the assassination of Dr. Martin Luther King Jr. was also the only one who refused to agree with the official FBI story?  Not so odd.  But what if I then told you that before the trial of supposed culprit James Earl Ray she was suddenly diagnosed with a mental illness, declared legally unfit to appear in court, and then placed in a psychiatric hospital against her will, for 10 years?  Not weird enough?  Well, what if I then told you that after being released in order to testify at a new investigation into the assassination, she disappeared *again* before she was unable to testify, only this time, there are no traces of her existing.  No obituaries.  No internet presence.  No medical records.  Not even a picture.  Join us as we detail one of the most odd aspects of the MLK assassination theories as well as the alleged conspiracy as a whole.
