A judge has sentenced the man convicted last week of killing a Lakeland police officer to life in prison without the possibility of parole.

Kyle Williams was found guilty of shooting Officer Arnulfo Crispin in a Lakeland park in December 2011.

On Tuesday, the prosecution and defense gave their closing arguments. 

Prosecutors told the jury Williams deserved the death penalty for coldly premeditating the murder of a police officer.

"The state is not asking for anything more than justice in this case," prosecutor Hope Pattey said. "But what I want you to understand, ladies and gentlemen, is that we are not asking for anything less than justice."

However, the defense argued that Williams had many fine qualities, and that the killing wasn't well thought-out. Defense attorney Byron Hilleman told the jury that Williams deserved a chance to live.

"What are we urging you to do, what we are pleading with you to do is to show mercy to that young man," he said.

The jury had the decision to either recommend life in prison or the death penalty, and the jury chose life in prison. 

Judge Donald Jacobsen accepted the jury's recommendation.

The sentence didn't really bring closure for the Lakeland Police Department or Crispin's family.

"The weight's never going to be off because we are never going to have Arnulfo back," said Police Chief Larry Giddens.

"No we are not happy with the verdict," said brother Frankie Crispin. "Because I believe that anybody who has no regard for life, especially for a law enforcement officer, deserves the punishment of the death penalty."

Kyle Williams' defense team now says they will file an appeal to his conviction within 10 days.
