MINNETONKA, Minn. (AP) — Officials say one of two construction workers injured in a trench collapse in Minnetonka has died.

The Hennepin County medical examiner's office says 48-year-old Jimmy Scott Klous of Onamia died late Monday morning in the emergency room of Hennepin County Medical Center in Minneapolis.

Klous and a co-worker were digging a trench for a road reconstruction project in Minnetonka when the dirt gave way around 10 a.m. Monday.

City spokeswoman Kari Spreeman says Klous was buried for about 20 minutes and was unresponsive when he was rescued. The other man also was taken to HCMC, where Spreeman says he was in "moderate" condition Monday.

The men are contract workers for the city and not city employees.

The OSHA division of the Minnesota Department of Labor and Industry will investigate.
