Bam Margera broke down while visiting the scene of the crash that killed his best friend, "Jackass" costar Ryan Dunn.

Dunn, 34, and his passenger, Zachary Hartwell, 30, both died in the accident when Dunn's 2007 Porsche crashed in West Goshen, Pa., about 35 miles west of Philadelphia, at 2:38 a.m. local time Monday.

Speaking at the crash scene Tuesday, Margera told WTXF, "I've never lost anybody that I care about. He's my best friend."

Emotional Margera added, "He was the happiest person ever, the smartest person, with so much talent. He had so many things going for him. It's just not right, it's not right."

Margera was in Arizona with friends when he received what he described as the "worst phone call I've ever got in my life."

He told WTXF that he had a premonition of the accident before he received the news.

"At 12:30 [local time], I just started punching out the windows of the rental van and ripping out the speakers, and I don't even know why," he said. "I wasn't mad at anything or anybody. If it was 12:30 there [in Arizona], that means it was exactly when he crashed."

Dunn's luxury sports car was found in a wooded area off the road "fully engulfed in flames," and both passengers were killed instantly.

Police who did an accident reconstruction said that Dunn's Porsche might have been traveling as fast as 130mph when it jumped a guardrail, flew into a ravine and burst into flames, myFOXphilly.com reported.

Officials were awaiting the results of a toxicology test to determine if alcohol played a role.

Margera earlier defended Dunn after movie critic Roger Ebert tweeted that "friends don't let jackasses drink and drive."
