Kenny Ring died in January 2010 after prosecutors said he was hit in the head with a baseball bat during a store robbery. Investigators maintain it was an inside job pulled off by one of the store's drivers - Nico Bowers - and his best friend Travis Sherman.
In an interview on the videotape recorded at the Knightdale Police Department, Sherman admits he was involved, but says he didn't kill Kenny Ring. Instead, he pointed the finger at another man, Chris Thomas, who has since been cleared.
On Friday, Ashley Klinger -- who is the mother of Thomas' child and was friends with Sherman -- told jurors Thomas wasn't at Domino's the night of the robbery and murder because he was with her that entire weekend.
"He didn't leave until Sunday afternoon, uh, Sunday evening," Klinger said.
She said she remembered that weekend well because she and Thomas had a threesome with a female friend.
That woman also testified and told jurors she too now has a child by Thomas.
She, along with Klinger's sister, backed up Klinger's testimony that Thomas was with them in Franklin County the night of the murder.
On cross examination Klinger said she cared deeply about Thomas, but not deeply enough to lie for him. However, she also said she couldn't trust him when it came to their relationship.
"When dating Chris, did he cheat on you," defense attorney Dan Dolan asked.
"Yes," Klinger said.
"Twenty times," Dolan asked.
"Probably," Klinger replied.
"Forty," Dolan said.
"It's possible," Klinger said.
Thomas was initially charged with murder but that charge was later dropped after investigators said they came to believe Sherman was lying and that Sherman was the one who hit Ring with the bat.
Nico Bowers is also charged in the murder and is awaiting trial.
Thomas is expected to testify. The alleged murder weapon was never recovered.
Sherman's attorney has said he's innocent and claims Knightdale police botched the investigation.
