A dump truck driver at a road construction site in Delano ran over and killed another worker who had gotten out of her vehicle, authorities said Thursday.

The collision occurred shortly after 8 a.m. Wednesday on E. Railroad Avenue, according to the Wright County Sheriff's Office.

Jacqueline J. Brueggemeier, 55, of Biscay, Minn., got out of her dump truck and was struck by another being driven by Tonya Sibila, 39, of Eden Valley, Minn., the Sheriff's Office said.

Brueggemeier's injuries "were severe, and she died at the scene," a statement from the Sheriff's Office read.

Brueggemeier was employed by WM Mueller and Sons of Hamburg. Sibila is a driver for Molnau Trucking of Belle Plaine.

Occupational Safety and Health Administration officials in Minnesota are investigating the workplace fatality, as is the Sheriff's Office. No charges have been filed in the case.
