The commonwealth has rested in the fourth day of testimony for the murder and kidnapping trial of Lawrence Stinnett.

If convicted, Stinnett could face the death penalty for those charges in connection with the slaying of former girlfriend Christina Renshaw back in 2006.

Items including bloodstained clothes and broken kitchen appliances were shown to jurors on Friday morning that were taken from suspects and Renshaw's apartment on the night of the alleged attack.

Following that, voice recordings of phone calls made by Lawrence Stinnett from jail were played.

Those phone calls, the commonwealth says, connect him to the crime.

"I stomped her, but I didn't try and kill her. You know what I'm saying?"

Those were the words of Lawrence Stinnett spoken by phone to friend Wanda Journagan shortly after the death of Christina Renshaw.

"I snapped on that one. Messed up my whole world there," he said in the recordings.

Friday's hearing brought audio tapings of Stinnett making two phone calls to Journagan and one call to another friend's mother from the Warren County Jail.

In them, he's heard saying that he's quote, "Struggling to keep his mind right."

He tells Journagan he's never killed anyone before.

"We heard eight different men having sex with her over a four hour period of time," he continued in the recordings.

Stinnett says he was motivated to drive from Oklahoma City to Bowling Green after he says he called Renshaw and heard her having an affair over the phone.

But authorities say while records show that phone call took place, interviews reflect that the affair did not.

"We found no one that indicated there was any sex that occurred or she was unfaithful to anybody," said Det. Brett Kreilein, with the Bowling Green Police Department.

On Friday, Kreilein displayed a number of items that have been tested for the presence of human blood.

Of those were a cowboy boot of Stinnett's and seven swabs taken from his left hand, all of which showed traces of Renshaw's DNA.

"This Exhibit 13 matches Christina Renshaw. This frequency of this population is one in 230-trillion based on the U.S. population of African American or Caucasian populations," said Chris Cohron, Warren County commonwealth attorney.

Stinnett, who is representing himself, chose not to cross-examine Friday afternoon.

At the end of the hearing, his appointed public defender Vince Yustas, filed motions to have Stinnett's murder charge amended and his kidnapping charge dropped citing lack of evidence for both.

Judge John Grise denied both of those motions.
