The charge is murder in the first degree, and if found guilty, a woman in Ocala may face the death penalty.
Emilia Carr is one of two defendants charged with the premeditated murder of Heather Strong in 2009.
The prosecution claims she and her then-boyfriend Joshua Fulgham tied Strong to a chair and tried to break her neck before suffocating her.
Strong's body was later found in a shallow grave in the outskirts of
McIntosh, Florida months after her cousin reported her missing.
Emilia Carr wore a suit to court Monday and Tuesday and was accompanied by her team of lawyers from Lake County, Candace Hawthorne and Brenda Smith.
It took two days for the jury to be selected. Circuit Judge Willard Pope finishing that process Tuesday afternoon.
The jury consists of six women and eight men. Two alternate jurors were selected.
With the jury seated, the trial will begin at 8:30 a.m. Wednesday morning.
Sources say Carr rejected to enter a guilty plea for a life sentence, leaving the prosecution seeking the death penalty if Carr is found guilty.
The trial is expected to last two weeks.
