Pretty much from the movie Taken.

Quote from another page:

"This is the GOAT of the year. John Eisennman lost his daughter to sexual trafficking at 19 years old. He did what a father should and researched HIMSELF  found out about her abduction and R E S C U E D her HIMSELF.. When he found out the person who sold her into the s3x trafficing was her 19 year old boyfriend. He met up with him and bludgeoned him and stabbed him to death in Nov. 2020. Well they found him[dead asf boyfriend] in Oct 2021 in the car he abandoned.  And now he sits here knowing his daughter is safe and growing up after he has already lived 60 years. Live your life to the fullest. Then make sure your spawn has the opportunity to do the same no matter what the sacrifice."

If all this is true I hope he gets nothing but a slap on the wrist.
