SIOUX FALLS — It’s been five decades since Ellabeth Mae Lodermeier was last seen, and the Sioux Falls Police Department is seeking any new information that could help find her.

Ellabeth was last seen at her home in the 300 block of North Indiana Avenue in Sioux Falls on March 6, 1974. When she didn’t show up to work the following day, coworkers joined her estranged husband, Gene, in conducting a welfare check at Ellabeth’s home.

Police records say that when the group arrived, Ellabeth’s home was locked and her car remained in the driveway. A partially eaten pizza was located inside, and flour was found to have been spilled on the floor.

Her purse and jacket, however, were missing.

Ellabeth and Gene were known to have traveled often in the immediate area, but it wasn’t until Sept. 20, 1974, that credit cards belonging to Ellabeth had been located in a train station bathroom in Dauphin, Manitoba, Canada, roughly 650 miles away from Sioux Falls.

Despite the discovery, investigators say no evidence points toward Ellabeth being in Manitoba.

More evidence wouldn’t be found for nearly two decades, when in April 1992, Ellabeth’s wallet, checkbook and more credit cards were found in a hole along the Big Sioux River to the east of Sioux Falls.

Authorities say Gene was the last person known to see Ellabeth, and that he is considered as a person of interest in Ellabeth’s disappearance.

Though Gene died in 2013, the Sioux Falls Police Department says it continues to search for any details related to Ellabeth’s disappearance or unusual behavior from Gene.
