New information today about why a former lawmaker may have gunned down his ex-fiancee.
Lexington police charged Steve Nunn with Amanda Ross' murder last night.
Court documents show Nunn reportedly told state police he was at the end of his rope, and wanted revenge.
Ross had taken an emergency protective order out against Nunn earlier this year, after an incident at her West Short Street townhome, where she was killed Friday.
Nunn reportedly left a seven page letter in his car, that mentions revenge and uses derogatory terms to describe Ross.
No date is set yet for Nunn to answer to the murder charge here in Lexington.
Under Kentucky law, Nunn would be eligible for the death penalty if he's convicted.
But a decision on that has not yet been made.
