MIAMI -

Closing arguments began Friday in the trial of a teenager accused of fatally shooting a couple at a Miami Gardens gas station in 2011.

Eric Ellington, 19, is on trial in the July 2011 shooting that claimed the lives of Julian Soler, 23, and Kennia Duran, 24. Ellington was 16 at the time.

Assistant state attorney Alejandra Lopez called Ellington a cold-blooded killer during her closing arguments.

"This defendant, while Julian is still with his hands in the air, stands above him with that gun and continues to shoot -- not once, but at least four to five more times," Lopez told the jury.

Lopez described in detail the evidence found at the crime scene, including Ellington's fingerprints. She also used the opportunity to once again show jurors surveillance video of the fatal shooting.

Defense attorney Herbert Smith cautioned jurors not to believe everything they see or hear.

"The issue is not how you feel about what happened," Smith said. "The issue is has the state proven with evidence."

Both victims' parents were in court.

So was Ellington's mother, who began crying hysterically and had to be escorted out of the courtroom.

Jurors began deliberating Friday afternoon.
