Sheila Graham-Trott was found guilty of murder Tuesday for the murder of her husband's lover. She was immediately sentenced to life in prison, the maximum sentence.

Trott, the estranged wife of former Indialantic mayor Daniel Trott, was charged with killing Kelly Brennan back in 2010. Prosecutors said Brennan was a friend who was having an affair with Daniel.

“Well the defendant was very careful in the way that she carried out the crime and left very little physical evidence to link her to it,” said prosecutor Samantha Barrett.

Barrett said Trott did make some mistakes -- which included taking her young sons to the crime scene. They testified against their mother.

The defense and the prosecution spent Tuesday giving their closing arguments.

During testimony Monday, a judge decided not to play a profanity-laced voicemail for the jury. The defense said Brennan's husband called the former mayor and ripped into him about the affair.
