CHICAGO (WLS) -- New details were revealed in court Thursday after the stunning discovery inside a Northwest Side home.
A woman has been charged with hiding her dead mother's body inside a freezer, which prosecutors say has been there for years.
While it was previously reported that the elderly woman was 96 years old, that may not be true after prosecutors said a calendar entry found inside the home said she died nearly two years ago.
Eva Bratcher, 70, faced a judge for the first time Thursday, charged with concealing Regina Michalski's death that appears to have happened on March 4, 2021.

Early this week, investigators discovered Michalski's body in a deep freezer stored in the garage of a two-flat apartment building where she and Bratcher lived in Portage Park.
The 96-year-old woman had apparently been dead for nearly two years. While prosecutors gave no motive for Bratcher hiding the death, they noted that an ID found in the home bore Bratcher's photo but her mother's name.
In addition to the false ID, investigators found a document in the home made to look like it was signed by Michalski - but dated after her apparent death, which Bratcher noted on a calendar as 2 p.m. on March 4, 2021.
A receipt found in the house showed Bratcher purchased a freezer from Abt a week after her mother's apparent death, prosecutors said.

"She did admit that after her mother died, she purchased the freezer approximately a week later and placed her mother in the freezer," said Cook County Assistant State's Attorney Michael Pekara.
No cause of death has been determined yet, and prosecutors said the medical examiner's office may need until the end of the week to completely thaw the body out for autopsy.
Prosecutors said police were also still investigating whether Bratcher collected her mother's Social Security checks or other benefits after her mother died. For now, she faces felony charges of concealing her mother's death and possession of a fraudulent identification card.
Two decades ago, as Sabrina Watson's mother was about to go to prison, she gave her 14-year-old daughter a disconcerting order.
If the girl's grandmother should die, bury her under a different name, Bratcher allegedly instructed, according to Watson.
"And I said why? And she said, 'Well if you bury her, idiot, under the name Regina Michalski, I won't get her checks anymore and I need those checks,'" Watson recalled.
Michalski's body was discovered after Watson, who lives in Kentucky, called the police and asked them to conduct a well-being check. "I just said, I'm calling [the police] and just having them do a welfare check," said Watson, 38. "What could go wrong? Apparently, everything."
Watson said she had scanned obituaries for years looking for her grandmother's name. Michalski had not been in good health when Watson last saw her decades ago.
Watson said her mother had blocked her number, and anytime she visited Chicago and stopped by the home, no one would answer.
Overcome by anxiety of the last few days, Watson had to be taken to the ER in Kentucky Thursday.
"Urgent care transferred me to the ER when my, they said, it's a heart problem, that the stress is affecting my heart," Watson said.
Estranged for years, Watson at one point took a drastic step to warn people about dealing her mother: She created a Facebook page titled "Keep Eva Michalski/ Bratcher in Prison."
"This page is to alert ANYONE that knows Eva Michalski (aka Eva Bratcher, aka Ewa Michalska and probably other aliases) that she is a DANGEROUS CRIMINAL!" the page says.
While it was only speculated at in court, Watson said she believes her mother's motives in concealing the death were financial.
"There's basically nothing my mother wouldn't do for money and if that means putting a body in a freezer, she will put a body in a freezer," Watson said. "My mother would use my identity falsely. The last time she did it. She used my first name and my maiden name and said that I was unable to work because I was taking in Chicago taking home my sick grandmother."
Court records show Bratcher was sentenced to four years in prison in 2010 for forgery in Lake County, Illinois.
In January of 2006, she pleaded guilty to felony counts of forgery in two cases and was given concurrent sentences of six months in the Cook County Jail and two years' probation.
Later in 2006, she was found guilty of misdemeanor counts of battery and violating an order of protection in two other cases, and she was sentenced to concurrent, two-year probation terms.
Bratcher completed her probation sentences without fulfilling the requirements, and she pleaded guilty to violating the terms of her release, records show. She was then sentenced to concurrent two-year prison terms, though she had accrued a significant amount of time served.
She has also faced a range of charges that were dropped, including battery, assault, retail theft, criminal damage to property, and reckless and disorderly conduct.
Prosecutors said Bratcher hid her mother's death from tenants in the building and neighbors by telling people her mother was in a nursing home.
One tenant, Brigitte Yanez, told the Sun-Times said she remembers a conversation she had with Bratcher a few months ago in which Bratcher talked about buying a gift for her mother.
"She would talk about her like she was still here," Yanez said. "I would be very confused because she had told my dad [that her mother] was in a home in Wisconsin."
In court, prosecutors also disclosed that Bratcher is a retired U.S. Army veteran. Records indicate she retired after just over 19 years of service 1994.
During a hearing Thursday, Judge David Kelly called the allegations "very disturbing" and said she would need to post $20,000 bond to be released on electronic monitoring.
Bratcher's defense attorney said she could afford a $5,000 bond but didn't indicate if she would be able to come up with the extra money and, if so, when.
She will be allowed to return to her building if she is released from jail, but the judge warned her about having "unlawful contact" with the other tenants of the building, who are potential witnesses.
Watson said she wants her grandmother, a Polish immigrant who grew up during the Nazi occupation of her country, remembered for more than just the gruesome disposal of her remains.
"She made these amazing Polish dishes that I will never taste again. And it's horrible that I didn't take the time to you know learn her recipes," Watson.
Bratcher is expected back in court Feb. 21.
