Kentucky man accused of killing lawman who arrested him

Authorities are investigating whether a long-running grudge led to the shooting death of an 82-year-old retired lawman.

They had crossed paths before: the career lawman and the man known around their small Kentucky town for having a mean streak.

Now authorities are investigating whether a slow-burning desire for revenge that began with an arrest a decade ago was behind last month's death of Herbert Proffitt, 82, who was gunned down in his driveway while he went to fetch the mail.
Charles Hammer, 81, is accused of killing the former police chief and sheriff, who arrested him in 2002 on charges of harassment, disorderly conduct and resisting arrest.
