Strolla said what may be an issue on appeal is the fact that the jury was not allowed to consider that if they found cause for self-defense on the murder charge, it could have been applied to all the charges.
"If he's given 60 years in prison and none of the charges are overturned on appeal, you are looking at basically life in prison," Strolla said.
Dunn claimed self-defense in the Nov. 23, 2012, Black Friday shooting, saying he saw what appeared to be the barrel of a shotgun after being threatened by Davis.
The shooting happened after Dunn asked the teens to turn down the loud music coming from their SUV. He fired 10 shots, three of which struck Davis, who died at the scene.
Dunn and his fiancée had stopped at the store at Southside Boulevard and Baymeadows Road to get a bottle of wine before going to their hotel after attending Dunn's son's wedding.
The teens were on their way to the Avenues Mall to go "girl shopping" and had stopped for the driver, Tommie Stornes, to buy cigarettes.
Following the shooting, Dunn and his fiancée, Rhonda Rouer, drove back to their hotel. They ordered a pizza, each testifying that Rouer didn't feel well because of what happened and it may be best if she ate something. They stayed at the hotel overnight and the next morning saw from news reports that a teen had died in the shooting.
The two then headed back to their home in Satellite Beach, and Dunn testified he called a friend who was a federal law enforcement officer to get advice about how to turn himself in. He was later arrested at his home.
At the scene of the shooting, the teens' SUV left the gas station after the gunfire and pulled into a connecting plaza. Three minutes later, they returned to the gas station, saying they were looking for help for Davis.
Dunn's defense attorney, Cory Strolla, said during the trial that three minutes was long enough for the teens to get rid of a weapon. He pointed out that police did not search that area until four days later.
The trial has gained national attention, especially in the wake of the George Zimmerman trial, in which he was acquitted of murder in the shooting death of 17-year-old Trayvon Martin, also a black teenager. State Attorney Angela Corey, the prosecutor in the Dunn trial, was the special prosecutor assigned to that case.
Demonstrators have remained outside the Duval County Courthouse every day since the Dunn trial began Feb. 3.
After being given the Allen charge Saturday afternoon because the jury said it was deadlocked on a count one of first-degree murder or any of the lesser included charges, jurors in the Michael Dunn trial asked the judge another question at about 6:20 p.m.
"We have reviewed the weaknesses of our position and have more to talk about," the question read. "If we are unable to agree and reach a verdict, is the entire case mistried or is the single count mistried?"
"Only the single count is mistried. Not the entire case," the judge answered. "If you've reached a verdict on the other counts, they stand."
Earlier in the afternoon, the jury said it had reached a verdict on four of the five counts against Dunn, but was unable to reach a unanimous decision on count one of first-degree murder or any of the lesser included charges.
The judge gave the jury the Allen charge, which urges them to come up with a verdict and gives them additional time to deliberate.
Less than an hour after the jury began its deliberations Saturday morning, the jurors sent out three questions:
- Is the defense of self-defense separate for each person in each count? Judge Russell Healey answered "Yes."
- Are we determining if deadly force is justified against each person in each count? Judge: "Yes."
- If we determine deadly force is justified against one person, is it justified against the others. Judge: "No. Self-defense and justifiable use of deadly force applies separately to each count."
