MICHELE'S FINAL WORDS REVEALED!

Reiner wife's heartbreaking last message to death row pen pal

- 

DEATH row convict Nanon Williams received an email from Rob Reiner's wife, Michele — his pen pal — just hours before the celebrity couple were slaughtered in a bloodbath allegedly by their druggie-past son Nick.

Williams, now 50 — who maintains he's innocent of fatally shooting Adonius Collier, 19, in a Houston park when he was just 17 in 1992, for which he's been sentenced to death — became pen pals with Michele during his more than three decades in the slammer.

And on Dec. 12, she, Rob, their daughter Romy, and friends Billy Crystal and his wife attended a production of Lyrics From Lockdown — a one-man show about injustice in the U.S. legal system based on Williams' life and writings.
