A Polk County jury found 21-year-old Kyle Williams guilty Thursday of first-degree murder in the 2011 shooting of Lakeland police officer Arnulfo Crispin.
Deliberations were well into a second day when the panel reached its decision.about 4:30 p.m. Deliberations lasted more than 14 hours.
"Justice has been done," said Frankie Crispin, Arnulfo Crispin's brother. "Now the next phase is to give him the death penalty or life in prison."
Frankie Crispin said he made eye contact with Williams during the trial.
"I was expecting to see some type of remorse," he said. "But actually what I got was a smirk on his face and a smile as if he was taunting, like, 'I'm gonna get away with this.' It was shocking to me because there was no remorse."
The family wants Williams to receive the death penalty.
"If the death penalty is given then that will be some closure for us," he said. "Obviously things will never be the same. My brother won't be back with us, but that's what all of us as a family are hoping for."
Jurors started deliberating just before noon Wednesday and were sequestered in a hotel Wednesday night.
Late Thursday afternoon, the judge sent a note to the jurors asking them if they anticipate the need for dinner and hotel accommodations again for the night.
The jury responded that a verdict had been reached.
The panel determined that Williams shot and killed Officer Crispin in December 2011 during a routine pat down in a Lakeland park.
The penalty phase of the trial is set for Monday.
After eight hours of deliberation on Wednesday, jurors adjourned for the night and reconvened 9 a.m. Thursday. They were sequestered in a hotel without televisions, radios or any other means to receive outside information about the case.
Around 5 p.m. Wednesday -- nearly five hours into deliberations -- the jury came forward with a question for the judge.
"The question is we feel the photos and maps are difficult to determine the appropriate positioning and distance. Would it be possible to go to the park?" the judge said, reading the question.
He immediately said no because "it would be inappropriate."
Closing arguments wrapped up late Wednesday morning. The prosecution laid out all the evidence in some tense moments just feet from the accused killer.
"He points that gun in the most vulnerable and most exposed part of his body and pulls the trigger," said Paul Wallace, state prosecutor.
Four of Williams' friends were with him that December night when Crispin came over to do a routine pat down in a Lakeland park.
"He simply ambushes him and executes him there in front of these guys," Wallace said.
All four pointed to Williams as the shooter during two weeks of testimony.
The defense offered another theory during closing arguments, that the men concocted a plan to blame Williams.
"They all lied. They contradicted themselves and each other," said Chris Boldt, defense attorney.
Right after the judge dismissed the jury to begin deliberations, Williams' attorney stood up and told the judge his client became upset because he now wants to testify.
The day before, he struggled to make a decision on whether to take the stand but finally declined with tears in his eyes.
