NASHVILLE, Tenn. - Testimony continued Thursday in the murder trial of Jerome Barrett.
Barrett is charged with first degree murder in the 1975 strangulation death of Marcia Trimble.
The nine-year-old disappeared while delivering Girl Scout cookies in her Green Hills neighborhood.
The case remained cold for three decades until DNA evidence put Barrett at the crime scene and he was charged in June of 2008.
Jurors on Thursday heard testimony from a Sheldon Anter, an inmate housed with Barrett in the Davidson County jail last year.
Anter testified the two spent time together and on multiple occasions, Barrett told him he killed Trimble.
"Jerome said, 'I have killed before and I have no problem killing you'," Anter testified.
Surveillance video of a jail fight between Barrett and another inmate was shown to the court.
The inmate accused Barrett of being a "baby killer."
In his testimony Thursday, Anter said Barrett confessed to the killing but claimed he did not rape the young girl.
Anter: "He said his DNA was on Marcia Trimble."Attorney: "Did he say anything else about DNA?"Anter: "Yes, he said it was on her, but not in her. He said he did not rape her, he killed her."
Much of Thursday's testimony focused on DNA evidence.
An expert testified DNA on slides from Trimble's autopsy did not match Barrett but DNA on her pant leg did.
The prosecution rested its case late Thursday afternoon.
The defense began calling witnesses shortly after 5 p.m.
The trial is expected to continue into the weekend. Watch the trial live at WKRN.COM.
Barrett was convicted earlier this year and sentenced to life in prison for the 1975 slaying of Vanderbilt student Sarah Des Prez.
