LOUISVILLE, Ky. (WHAS11) -- After two days of legal wrangling and an initial refusal to testify, Joey Banis took the stand on Friday, May 24, in front of a packed courtroom, implicating his ex-lover Jeffrey Mundt in the murder of Jamie Carroll.
"Jeffrey Mundt stabbed and shot Jamie Carroll and then forced me to help him cover it up," Banis testified.
Banis said Carroll was murdered on Dec. 15, 2009 after a night of sex and drugs involving all three of the men.
His body was discovered in the basement of Mundt's Old Louisville mansion in June 2010.
Banis testified he saw Mundt shoot and stab Carroll.
"This was a life or death struggle. They were fighting. It all happened extremely quickly. Jamie yelled out ‘Joey, Joey, help me,'" Banis testified.
Banis said he didn't immediately flee or go to police because he was afraid Mundt would implicate him in the murder, since he was a convicted felon.
Banis said Mundt also threatened to harm him.
"I thought Jeff was perhaps was going to shoot me. And I told him so. And he said if I didn't say anything, he wouldn't. But if I did, he would kill me and kill my family. And after what I had just seen, I absolutely believed him," Banis said.
Banis also testified about helping Mundt dispose of Carroll's body in the basement of Mundt's home.
"It's a pretty creepy place. Creepy. At this point, there was a dead body, blood dripping onto a dirt floor. All kinds of tools," Banis said. "I held the body. He sledgehammed Jamie's knee caps, and we folded him into a position where he would fit into the container."
During cross examination, Mundt's attorney Steve Romines repeatedly questioned Banis about his lengthy criminal past and about accepting a deal in exchange for his testimony.
The prosecution has not yet rested.
The trial will continue at 10 a.m. Tuesday, May 28.
