Circumstances of Disappearance​

On March 6, 1974, police were called to Ellabeth's home after she failed to show up to work. Her car was in the driveway and the house was locked. Upon entering, the police found pizza laying on the kitchen floor with one slice missing, spilled flour, and a loaf of homemade bread left rising on the counter.

In September 1974, three of Ellabeth’s credit cards were found in the bathroom at a railway station in Manitoba, Canada. In April 1992, a farmer found Ellabeth's purse and wallet in a hole along the Big Sioux River near Highway 42.

Ellabeth disappeared three weeks before her divorce was set to go to trial. According to a deposition she gave, Ellabeth said her husband was abusive. Although he was a prime suspect in her disappearance, no charges against him were ever filed, and he died in 2013.
 
Ellabeth Mae Lodermeier was last seen five decades ago at her home near downtown Sioux Falls. Her estranged husband, Gene Lodermeier, reported her missing on Mar. 7, 1974.

In September of 1974, Ellabeth’s credit cards were found in the women’s bathroom at the Canadian National Railway in Dauphin, Manitoba, Canada. A check of that area found no evidence that Ellabeth had ever been there.

In 1992, Ellabeth’s wallet containing her checkbook and credit cards were found in a hole along the Big Sioux River.

Details of Disappearance​

Ellabeth was last seen at her home the 300 block of north Indiana Avenue in in Sioux Falls, South Dakota on the evening of March 6, 1974. Her boyfriend also lived in Sioux Falls, but was out of town on the day she disappeared. He agreed to call her between 9:00 and 9:30 p.m. He did call, three times, but each time the upstairs tenant answered the phone, and he was never able to talk to Ellabeth.

She was estranged from her husband, Gene Vernel Lodermeier, at the time, and they were in the process of a divorce. It was her co-workers who told him, the next morning, that she hadn't shown up for work and they couldn't find her.

Gene went to Ellabeth's residence and found a loaf of bread rising in the kitchen, flour spilled on the floor, and a fresh pizza with one piece missing. Her car was parked in the driveway, the house was locked and nothing was missing except her coat and purse. She has never been heard from again.

Later in 1974, Ellabeth's credit cards were found in a women's bathroom at the Canadian National Railway in Dauphin, Manitoba, Canada. This is nearly a ten-hour drive north of Sioux Falls, and authorities could find no sign that Ellabeth had ever been there. They think probably someone else put the cards there in an attempt to distract the investigation.

In 1992, eighteen years after her disappearance, her purse, wallet and checkbook were found on the banks of the Big Sioux River near Highway 42 and south Riverview Avenue, east of Sioux Falls. A search of the river turned up no sign of her or her body.

Ellabeth's family had never approved of Gene, and described him as controlling and abusive. He would even disable her car occasionally to stop her from going to her college classes. In 1973, Ellabeth filed for divorce and said under oath the Gene had abused her, something he later denied.

She soon met and began seeing another man. Her boyfriend immediately returned to Sioux Falls when he realized she was missing, went to the police, and took and passed a polygraph exam. He was cleared of suspicion in her case.

Gene, who was the last person to see her, is considered a person of interest in her case; Ellabeth disappeared three weeks before the divorce case was to go to trial. In February 1978, nearly four years after she disappeared, Gene filed a lawsuit against the city of Sioux Falls, claiming he had been harassed by the six police officers and jailed for nine days. The officers were cleared of harassment, however.

Gene ran into trouble with the law numerous times after his wife went missing. The most serious conviction was in 1989, when he was sentenced to 45 years in prison for grand theft. He was also accused of putting a pipe bomb in a police officer's car in 1977, and of try to have two Sioux Falls police officers killed, although none of those charges ever it to court.

In 2002, after serving 13 years of his sentence, Gene was paroled. He died of natural causes in 2013, at the age of 66, without having ever remarried. Ellabeth's parents are also dead, and her sister died in 2016, but her brother and former boyfriend are still alive.

Ellabeth was born in Billings, Montana, and later her family moved to Aberdeen, South Dakota. She attended Northern State University in Aberdeen before transferring to Augustana College in Rock Island, Illinois. She graduated from Augustana in 1972, with a bachelor's degree in social work, and worked as a social worker afterwards.

During her marriage, she and her husband had traveled throughout the midwest, including all over South Dakota and in northwest Iowa and southwest Minnesota.

Her case remains unsolved and foul play is suspected.

Extract from the obituary: "He and his mother managed the family partnership, Gene was responsible for maintenance and repairs. Gene enjoyed riding dirt bike on the trails in the Black Hills of South Dakota. He enjoyed his personal relationships with his many rental tenants. He could repair anything to working condition."
Jerry said he called her three times, but each of them the upstairs tenant answered the phone... Could the tenant be a friend of Gene? It appears he still had a key of the house, but if he entered the house, Beth would have screamed, she probably would have asked for help... And no one heard a thing?
It would be great to know which properties he and his family managed... Maybe her remains are there.
This is very interesting. I wish there would be some way to find out about the properties.

I wonder if Ella is still inside one of those properties or even buried there and then in 1992 one of those properties was sold or being cleaned out and that is why the purse was disposed at the River bank.

Someone had that purse in some storage for all those years.
Does anyone know the month in 1992 that the purse was found?
