David Grunwald knew too much.

That’s the reason Bradley Renfro said his friends killed the 16-year-old from Palmer in 2016.

After three days of testimony, Renfro still hasn’t said who shot and killed Grunwald, but on Friday he described the moments leading up to the crime scene on Knik River Road.

Renfro said he didn’t know what was going to happen after Dominic Johnson pistol-whipped Grunwald the night of Nov. 13, 2016. He thought they were going to drop Grunwald off somewhere, but soon realized something worse was in the works.

Erick Almandinger told him Grunwald wasn’t going home that night.

“When they started talking like that, I was just like, ‘What are they going to do? Kill him,’” Renfro said. “That’s what I was thinking. I didn’t say anything at that point.”

Renfro recalled Grunwald quietly crying in the backseat of his Ford Bronco as the group drove him to his death. He claimed he wanted to drop Grunwald off in Sutton or Jim Creek, at popular places where someone might find him.

Renfro said it was Austin Barrett who decided Grunwald needed to die.

“He said, ‘You can’t go home, you know too much.'" Renfro said. "That’s when he said, ‘I’m going to do this.’ Then Dominic said, ‘Do what?’ He said, ‘we gotta kill him.’”

Renfro said Grunwald was still conscious as they drove to the end of Knik River Road then turned around when they reached the lodge. As they were driving back, Barrett told Johnson to pull over near Mile 7.

“I didn’t understand how this was unraveling so fast,” Renfro said.

“Did you say anything to David yourself,” Defense Attorney Chris Provost asked.

 “I couldn’t look at him anymore. He had dried blood still on his face. I couldn’t see that anymore,” Renfro said.

The defense will continue with a fourth day of direct examination on Monday. Provost has spent three days meticulously going over statements Renfro made to Alaska State Troopers in three interviews before he was arrested.

Closing arguments likely won’t be until later next week.
