What would YOU do if you saw a violent kidnapping in progress?
One key witness in the Aniah Blanchard case says he initially kept his mouth shut instead of going to cops because his wife told him it was best to "stay out of it."
The horrible revelation was just made in an Alabama courtroom Wednesday, where officials are trying to prove Ibraheem Yazeed forcibly shoved 19-year-old Aniah Blanchard into her car on Oct. 23 -- the last night she was seen in public.
Blanchard -- who's still missing and at this point presumed dead -- is the stepdaughter of UFC fighter Walt Harris.
During Wednesday's hearing, officials say the witness saw Yazeed forcing Aniah into her car at the Chevron station and leaving the scene ... but he did NOT immediately go to police. Instead, he confided in his wife who told him it was best to not get involved. Unclear why she felt that way.
