Both sides have now rested in the Everett Miller double murder trial.
Miller was convicted of the 2017 murders of Kissimmee police Officer Matthew Baxter and Sgt. Sam Howard.
He now faces the death penalty and the jurors should have the case sometime Wednesday.
Closing arguments are expected first thing Wednesday morning.
TRENDING NOW:
Miller decided not to testify in his own defense and his legal team rested in the penalty phase of his double murder trial.
Miller's defense called witnesses Tuesday who said they believe he suffered from post-traumatic stress disorder.
On Tuesday afternoon, the state started calling rebuttal witnesses, including a man who claimed Miller pulled a gun on him at a cookout in 1992, while Miller was in the Marines.
"Put it to my head and asked me what we doing out here," said Wendell Glover.
Miller was arrested in that incident, but not charged criminally.
The defense tried to keep Glover from testifying because he couldn't identify Miller years later and because the incident had happened so long ago.
But prosecutors seemed to be trying to show Miller made a habit of pulling guns.

A psychologist for the state said he didn't believe Miller suffered from PTSD.
"Mr. Miller has a history of getting angry and grabbing a gun," said Dr. Michael Gamache, a psychologist for the state. "And it starts way before this."
In addition to the events in 1992, the state pointed to an incident in the weeks before the murders occured, in which Miller went to retrieve an assault rifle after he was challenged for walking around in his boxer shorts.
After both sides rested, they spent some time going over the jury instructions.
