Goblin Valley Rock Toppler Recently Claimed Disabling Injury

INSIDE EDITION has learned the man who toppled an ancient rock formation in Goblin Valley State Park had previously claimed to have a disabling back injury.

He's the knucklehead who whooped it up after destroying a national treasure—a 200-million-year-old rock formation that dates back to Jurassic times.

Now, Boy Scout leader Glenn Taylor finds himself between a rock and a hard place.

The guy who had the strength to topple an ancient rock formation at Utah's Goblin Valley State Park actually filed a personal injury lawsuit just weeks ago, over injuries he claimed to have suffered in a 2009 car crash.

Taylor's suit claims he "sustained serious, permanent and debilitating injuries and damages" in the accident.

Now, some are wondering how a disabled man could topple a 2000-pound rock, including Alan MacDonald and his daughter, Cassie, the two people named in the suit.

INSIDE EDITION's Paul Boyd asked the MacDonalds, "What does your gut instinct tell you after looking at this video, considering the lawsuit that you and your daughter are facing?"

Alan answered, "When I see that video, I just see a large, strong, able-bodied man pushing a big rock off the pedestal. I don't see a legitimate injury."

Cassie MacDonald, now 20, was 16 when the auto accident occurred. She admits it was her fault.

"I hit the cars in front of me, just pulled over to the side of the road, talked to the policeman, got everything sorted out," said Cassie.

Which is why they were shocked by the lawsuit.

Alan said, "I understand accidents happen, and Cassie caused the accident. I'm just surprised it's surfaced four years after."

Taylor wasn't pleased when asked about it by a reporter who said, "You recently filed a personal injury lawsuit saying you're debilitated because you were in a car crash."

"Yeah, from four years ago," said Taylor.

"You didn't look very debilitated in that video," said the reporter.

Taylor responded, "You didn't see how hard I pushed."

Taylor's lawyer refused to comment on this matter with INSIDE EDITION, adding that Taylor has been receiving death threats over the controversial video.

Taylor and his companions claim he toppled the rock to protect others, since it was so unstable.
