Children of woman who made $7.6 million off the sale of Sue the T-Rex found on South Dakota property battle each other in court for a share of their inheritance after she named one of the four the single heir

The children of a woman who made whopping $7.6million off of the sale of Sue the T-Rex found on their South Dakota property in 1990 have now started to feud about what is left of the sale money and her estate. 

The father, Maurice Williams died in 2011 and the mother, Darlene Williams died in 2020. Though they shared four siblings together, only three of them are involved in the legal dispute. 

Records revealed that Darlene had two wills- one filed in 2017 listed her daughter Sandra Willimas Luther in charge of the estate, and one from 2020 that listed her as the executer and sole heir. 

Darlene's other daughter Jacqueline Schwartz then questioned if the most recent will was legal as she said her mother was severely ill when she signed the document. 

The legal document also cited that Darlene wished that in her death, she had hoped that her children would find peace and become a family again after years of being at odds. 

When fossil hunter Sue Henderson and her team found the massive dinosaur skeleton on Maurice and Darlene's property, legals battles over ownership rights quickly ensued. 

It took six people and 17 days to completely dig up the large fossil from the ground Cheyenne River Reservation. 

The couple ended up claiming the rights of the discovery before they put Sue up for auction and The Field Museum in Chicago made the highest bid. 

According to the museum's website, funds for the dinosaur were supported by other companies like McDonald's. the Walt Disney World Resort, and 'private donors'. 

Sue the dinosaur, who was named after her discoverer was then transported to Chicago where 12 museum employees spent more than 30,000 hours preparing the skeleton. 

In August 2021, a judge appointed Jaqueline as the special administrator of the estate, according to Kelo News. She then went on to continue that role into February 2022. 

She claimed that when her late mother signed her second will, she was extremely sick and there was no witness in the room with her due to Covid-19 restrictions. 

Jacqueline also decided to contest the sale of their mother's Spearfish home just two weeks before Darlene passed. 

Court records revealed that $225,000 in proceeds eventually made their way to the couple's son Carson Williams. 

The most recent document filed in early 2023 asked permission to bring claims against both Sandra and Carson, and possibly Dakota Title, the insurance and escrow closing service for the estate. 

The new legal document alleges that there were possible misappropriations of funds and fraud. 

DailyMail.com reached out to Sandra, Jaqueline and Carson but did not receive a response. A trial date for the family's legal feud has not been scheduled yet.  

Sue the dinosaur is known as the largest Tyrannosaurus rex ever discovered, and also the most complete fossil at 90 percent.

The fossil's discovery not only allowed spectators to witness her in person but has also allowed scientists to conduct important research on 'species’ evolutionary relationships, biology, growth, and behavior than ever before,' according to The Field Museum's website. 

Sue can be found on display at her permeant home in the 'Evolving Planet' gallery near the Genius Hall of Dinosaurs.
