With Kyle Williams’ guilt already decided by the jury, Monday was about how Arnulfo Crispin's murder in a Lakeland park impacted his family, friends and coworkers.

Crispin's sister cried as she told the jury how Crispin was killed on her son's birthday.

"He was taken on his birthday and it breaks my heart to see my son stare at his photo,” said Brenda Crispin.

Crispin's father got so upset on the stand he said something he shouldn't have but the judge denied a request for a mistrial.

“That man should not have taken my son's life,” said Thomas Crispin, through an interpreter.

Crispin's police supervisor talked about a chair left in a meeting room in Crispin's honor.

“That lone empty chair that will never again be filled by Arnulfo Crispin speaks volumes of the impact this tragedy continues to have on members of Charlie Squad,” said LPD Capt. Rubin Garcia.

Kyle Williams’ friends and family also got to speak on his behalf. They described him as a caring young man who would help out in hard times.

"He told me everything was going to be all right,” said Shimbria Watson, Williams’ cousin.

Attorney: “And was it?”

Watson: “Everything went just fine.”

"I love him," Williams' stepfather, Reginald Mitchell, said. "He is my son. He is an honorable young man."

And just like the guilt-innocence phase of the trial, Williams didn't take the stand to speak on his own behalf.

The prosecution and defense will give closing arguments Tuesday. Then the jury will start to consider whether to recommend life in prison or the death penalty.
