Kentucky Mayor Killed: Hickman Mayor Charles Murphy Shot By Thomas Joseph 'Tommy' Lattus

A 30-year-old gunman allegedly killed the mayor of a small Kentucky town on Monday, because he was angry about the mayor's romantic relationship with his stepmother, according to The Associated Press.

Thomas Joseph Lattus walked into the Hickman police station at 1 a.m. that morning and told cops in the western Kentucky city of 2,500 that he'd shot second term mayor Charles Murphy, 68, in Murphy's home, Kentucky Public Radio says.

Shortly after Lattus confessed to the killing, a neighbor reported hearing a gunshot near the mayor's home.

An officer found Murphy's unresponsive body in his bedroom and the side door to the home showed signs of a break-in.

Police said multiple shots were fired, although officials did not reveal how many times Murphy was hit.

Murphy and Lattus' stepmother, Carole Lattus, had an on-again, off-again relationship that lasted for years, according to CBS News.

Murphy's brother, Fred Murphy, told CBS that his sibling had recently become worried about Thomas Lattus, who had started dropping in on the mayor.

Lattus has been charged with murder and is expected to be arraigned on Tuesday, according to media reports.
