The station reports that a letter from the mother, Jessica, to Edina Realty, led the real estate agency to pull the home off the market.
The four-bedroom home was where Jessica and her three daughters lived until July 10, when their father, Schaffhausen, was arrested and charged with killing all three.
Schaffhausen's mother wanted the house sold."Edina Realty was contacted by the grandmother of the victims," said Maria Verven, spokesperson for Edina Realty.
But the letter written by the girls' mother, and posted on a Facebook page dedicated to them, gave Edina Realty what they needed to walk away from the deal.
Jessica wrote, "What you may not have thought through in accepting this job is that if you do succeed in selling it, that you will allow their murderer to not only benefit financially but will also disquality him from the public defender he is using. Which means that the entire criminal trial process would be set back drastically."
"We did not realize that Mr. Schaffhausen could actually benefit from the sale of the property and as soon as we realized that, Edina Realty pulled the listing," Verven said.
Jessica wrote, "I understand that a sale is a sale for you but I needed to let you know exactly what you are contributing to and if you can still sleep at night with that knowledge then by all means move forward as your conscience dictates."
She signed the letter, "a grieving mother hoping for some kind of justice."
Edina Realty has nothing to do with the sale of the home as of Friday.
The four-bedroom home in River Falls was listed for $229,900.
Aaron Schaffhausen is accused of killing his three daughters - 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia.
He is due in front of a judge on Dec. 3.
