MINNEAPOLIS (AP) - A report says the death of a construction worker atop the new Minnesota Vikings stadium last week happened after he slid down a roof, broke through a guardrail and fell to an elevated platform.

The Star Tribune (http://strib.mn/1JwIqI3 ) reports the description was posted Tuesday on the state Department of Labor and Industry’s fatality investigation page.

The report says both Jeramie Gruber, who died, and a second worker fell while installing a solid roof. The worker who survived struck a post that stopped him.

The update gives no indication when the investigation will be complete.

The two men were employees of Mortenson Construction’s subcontractor Berwald Roofing Company of North St. Paul.

The surviving worker was released from HCMC after receiving 48 stitches for a deep cut to his leg.
