The trial of a Marco Island lady accused of killing her boyfriend continued Friday with opening statements and testimony from state witnesses who described their encounter with the lady and the bloody bed room they discovered on the scene.
Lisa Troemner, 27, faces a cost of second-diploma homicide. Prosecutors say she fatally stabbed her stay-in boyfriend, Trevor Smith, 30, of their house on Park Avenue throughout an argument Dec. 2, 2014.
If convicted, she might resist life in jail.
Six jurors and three alternates have been chosen Thursday after three days of jury choice.
The state and protection introduced their opening arguments Friday morning.

The impetus for the ongoing argument, Rumley said, was Smith staying out “too late” at a friend’s house.
Troemner was upset by that, Rumley said, and went out herself, going to a bar and cheating on Smith.
When Smith found out, she said, he was upset and the two began arguing.
The insults and verbal threatening eventually pushed Troemner “over the edge” and caused her to stab Smith, Rumley said.

All the blood at the scene was Smith’s and Troemner had no injuries but a self-inflicted wound, prosecutors said.
“The defendant stabbed the victim because she was mad,” Rumley said. “She was mad because he called her names. He wouldn’t stop talking about how she had cheated on him.”
However, Troemner’s defense attorney, Donald Day, painted a different picture of the events that night.
Day said his client was in “stone-cold fear” of Smith and had been verbally and physically abused for…
