Family friends say the woman is a 35-year-old mother of four. Two of her children, a boy, 11, and a girl, 14 were discovered.
A bailiff was conducting her eviction at her Detroit townhouse at the Martin Luther King Apartments in the 800 block of St. Aubin Street near Lafayette Central Park, when he found the two bodies.
"One of the community members here at the Martin Luther King homes approached our officers," Detroit Police Chief James Craig said. "And they advised they knew where the parent was located. Because during the eviction, the parent was not around.
"From the information from that community member, we responded and detained her for further investigation."
It is unclear how long the bodies had been in the freezer. The mother's two other children are in protective custody.
Family members, friends and neighbors grappling with the incident held a vigil to remember the two children.
Those who know the mother, called her "Angel," but inside her apartment was a hellish discovery prompting a makeshift memorial.
Words written on a poster designed to add a bit of beauty to an otherwise ugly scene - along with balloons and stuffed animals.
"They didn't deserve that," said Cory Turner. "They are kids, they didn't deserve that."
"She was a nice lady, always spoke to everybody," said Jessica, one of the woman's neighbors. "She was always nice with the kids, she kept her kids to herself."
Tori Childs is a close friend of the mother and she says whatever happened, how it happened, she simply wishes she could have saved those two young kids.
"She said 'Tori, I'm sorry' and then the police officer put her in the car and drove her away," Childs said.
The children were found inside a stand-alone freezer.
"When they were taking her stuff outside from the backyard, like the freezer had the blood on it," said neighbor Coretta Marion. "We were all outside watching it, but it was sad."
Neighbors say the mother would always talk about her kids but they were rarely seen.
"I only met Stevey and Stoney, the boy and the girl that passed away - I met them through the door," said Jessica. "They waived at me from the door and that was it."
Neighbors say they haven't seen the two children found in freezer for over a year.
"At one point in time her kids were always outside but after awhile they stopped coming outside," Jessica said.
Neighbors described the mother to FOX 2 as an "overprotective parent" and said she would even go on Facebook to talk about how much she loved her children.
Some neighbors say her children were home-schooled. Others say she told them the children were with other family members.
"She gave an excuse, an excuse to where you don't have to keep asking," Jessica said. "She was real to herself."
What isn't clear is what ultimately happened to the two children. The investigation is just beginning as police are waiting for autopsy.
FOX 2 spoke with a couple neighbors who saw the mother as early as Tuesday morning when the dumpster arrived as part of the eviction.
They said she had tears in her eyes but still no one expected this would be the outcome.
