Harvey Updyke, the notorious Alabama football fan who poisoned Auburn’s Toomer's Corner trees in 2010, has died. He was 71.

Bear Updyke, Harvey’s son, told Al.com that his father died Thursday of natural causes in Louisiana.

Harvey Updyke became known among Alabama fans in 2011 when he admitted to “The Paul Finebaum Show” that he poisoned the trees on the campus of the school’s chief rival.

“Let me tell you what I did,” Updyke said on the live radio show. “The weekend after the Iron Bowl, I went to Auburn because I lived 30 miles away, and I poisoned the two Toomer's trees. I put Spike 80DF in 'em. They're not dead yet, but they definitely will die.”

Updyke was convicted of felony criminal damage to an agricultural facility for the crime in 2013 and spent more than 70 days in jail. He was ordered to pay $800,000 in restitution, but according to court records, only $6,900 had been paid by last October.

Updyke’s first son was named after legendary Alabama coach Bear Bryant. He named one of his daughters Crimson Tyde.
