— The Boulder County Sheriff’s Office is looking into reports that a boulder on the western side of the town of Boulder was raised on the night of Nov. 5.

Boulder County Sheriff Tom Burch said a local company was excavating a hillside and found the boulder.

A crew from the company was hired to raise the boulder on Friday night, but Burch did not know when the boulder was raised or if it was raised by accident.

“There were no reports of any injuries or anything, but that’s just the kind of stuff that happens when you go down the road and try to get a job, it’s hard to tell,” he said.

Burch said he doesn’t know what caused the boulder to rise, but he has spoken with the Boulder County Medical Examiner’s Office to investigate.

Branch’s father, who was hiking with him on Nov. 6, told the AP he believes the boulder raised by the crew was made from concrete and that his father was in the process of building a house when he fell and hit his head on the rock.

Bureau of Land Management employees were also on the hillside when Burch’s father fell, according to the AP.

“I’m going to be a little more careful because I’m worried about my dad,” he told the paper.

Bower said he has not been able to contact his son.
