Authorities say asphyxiation killed a dry-ice delivery driver last week outside a McDonald's in Spring Lake Park.

Amos Nagbe, 58, of Brooklyn Center, was identified Sunday as the truck driver who was overcome by a chemical leak in his truck Wednesday while at the fast-food outlet on Hwy. 65 north of 81st Avenue NE., according to the Midwest Medical Examiner's Office.

Nagbe "died as a result of asphyxia due to exclusion of oxygen," a statement from the examiner's office read.

He was found dead about 9:30 a.m. in the back of the truck, where he was checking on some sort of "mechanical failure" and was overcome by liquid carbon dioxide while trying to fix the problem, a statement from the Sheriff's Office read.

The leak prompted a call for a hazardous materials team to respond to the scene, according to emergency dispatch audio. However, there was no danger to the general public, the Sheriff's Office said.
