Love from the beyond

 A cold blooded murder,
Down the path they walked,
The victim was wrapped,
Bloody fingerprints mapped
Only to realize,
The murderer had died.

The killer was long gone,
Committed suicide,
Because Ann, his lover,
Jilted him for another.
Dejection consumed him,
The affair was very grim.

The deceased wasn't Ann.
It was a man who tried
To harass her, in vain.
Ann's lover reached the lane,
Took the rouge's life away.
Ann saw that his love stayed.
