It's been 3 years since convicted murderer Aaron Hernandez killed himself in his prison cell -- but his fiancee is still showing love.
Shayanna Jenkins posted a throwback photo on April 19th -- showing the ex-NFL star holding their then-newborn daughter roughly 8 years ago.
"The love between father and daughter knows no distance," Jenkins wrote ... "We think of you today. May you Rest in Peace and continue to watch over us!"
Of course, not everyone remembers Aaron as a loving family man -- in fact, many know him as a bloodthirsty, unstable maniac.
