LEE COUNTY, Fla.-  An accused killer's fate is now in the hands of a jury.  Closing arguments concluded Monday in the capital murder trial of Robert Dunn.  

Dunn is charged with gunning down his estranged wife nearly five years ago at the Bobbie Noonan Child Care Center in Cape Coral.  Christine Lozier-Dunn was a teacher at the daycare.  The alleged crime happened in front of dozens of two and three year old children, including the couples daughter.

Closing arguments began Monday with a bone-chilling statement by prosecutor Marie Doerr.

"This case is about domestic violence at its ugliest.  A wife and mother shot and killed by her husband and the father in front of their child in a daycare center," Doerr said.

Prosecutors reminded jurors of previous testimony from witnesses it called.  Several witnesses said Robert Dunn was "focused" on killing his wife on January 25th, 2008.

Prosecutors said the crime was calculated and planned in advance by Dunn who purchased a firearm and ammunition days before the shooting.

During its closing argument, however, the defense painted a different picture of a "chaotic scene" and "tragic accident" where a drunk Robert Dunn acccidentally fired.

"To suggest that Mr. Dunn went to the daycare on January 25th to commit a murder of his wife because he received an income deduction order letter and proposal is absolutely preposterous," defense attorney Tracey Redd said.

Prosecutors rebutted Monday by bringing up the couple's two year old daughter who witnessed her mother's death.

"His young child was right there.  He was focused on one thing, killing, excuse me for the language he used, killing the (expletive). That's what he was focused on," prosecutor Bob Lee said.

Prosecutors are looking for guilty convictions for first degree murder, armed burglary, and child abuse.

The jury will be given verdict instructions at 9:30 Tuesday morning, and deliberations will begin shortly after.

If Dunn is found guilty, there will be a penalty phase of the trial, in which the death penalty is a possibility.
