Two U.S. Fish and Wildlife employees were killed when a driver hit them in a parking lot Monday evening in southeast South Dakota.

Dr. Robert Allan Klumb, 46, of Pierre, and Maegen E. Spindler, 25, of Cazenovia, N.Y., were in the Pickstown area doing field work, said Scott Larson, field supervisor in the Pierre Fish and Wildlife office. Pickstown is next to the Fort Randall Dam on the Missouri River.

Around 8:45 p.m., Ronald Ray Fischer Jr., 28, of Lake Andes, was driving a 2003 Chrysler Town and Country minivan on U.S. Highway 18 when he failed to stop at the stop sign at the T-intersection of state Highway 46.

The van traveled into the Dakota Inn parking lot, where it struck and killed Klumb and Spindler, and damaged two vehicles.

According to the Fish and Wildlife Service website, Klumb was the lead research biologist in the Pierre office.

Fischer, who was seriously injured, was airlifted to Avera McKennan Hospital in Sioux Falls. He remained in the hospital Tuesday.

Lt. Alan Welsh of the South Dakota Highway Patrol said lab results of Fischer’s blood are pending to determine whether he was drunk. Witnesses were still being interviewed.
