"It's like living in a nightmare that you don't wake up from," Miller told our sister station KTRK's 13 Investigates team.
In 2020, Miller buried her 12-year-old son, Tyree, who she said died by suicide.
Five years later, her 20-year-old son, Markeveon, died in a car crash.
"Being a mother that buried two children in less than five years apart from one another, it's devastating," Miller said.
The only peace Miller said she found was in a memorial room she built just for her sons. A glass case in the room features photos, ashes and other treasures she has to remind her of her sons.
"I watched you as a child. I can watch you while you're here," Miller said. "I'm able to come in here and sit in my memorial room for them and talk to them when I'm feeling down or when I need that extra strength."
But Miller said that peace was shattered in November when police raided A Community Funeral Home in the Third Ward.
Miller said she worked with Unique Green, who is listed as the president of A Community Funeral Home, for both of her sons' services.
"When I heard the name, because the name stands out, this is the same person that I had an issue with. This is the same person that I have an open case with, with an insurance company," Miller said.
When the funeral home was raided in November, police were seen hauling out boxes of ashes and said it was part of an investigation into potential identity theft of the dead.
Green was detained during the raid but released that same day.
Now, eight months later, Green was charged on Tuesday with five felonies, including forgery, theft and tampering with a government record.
Charging documents accuse Green of forging documentation to receive a funeral director and embalming license.
The charging documents also say detectives located "a Home Depot bucket filled with organs, and 48 boxes of cremated human remains."
Some families had been waiting for the remains of their loved ones since 2023, according to police.
None of the charges filed against Green this week are related to Miller's case.
Instead, 13 Investigates learned the new charges stem from allegations that Green stole a man's estate and forged or tampered with government documents.
A search warrant filed in the case says the deceased man's family lives out of town and paid Green to conduct funeral services.
Documents accuse Green of later forging a will on the man's behalf and stealing his nearly $2.2 million estate, including his home, cars and investment accounts.
Our team found a will filed in Harris County months after the man died, saying that he left "my entire estate to my long-term partner and common law spouse, Unique M. Green, in recognition of her unwavering love, devotion and support."
The man's family told investigators they had never heard of Green until they contacted her for funeral services.
13 Investigates found criminal charges against Green in Harris County dating back to 1998, when she pleaded guilty to forgery and received deferred adjudication.
In 2007, Green pleaded guilty in federal court to submitting fraudulent claims to FEMA for funds after Hurricanes Katrina and Rita.
The indictment says she used fake Social Security numbers and addresses. Green was sentenced to almost four years in that case.
Since then, Harris County court records show Green has served sentences for several counts of forgery, assault, theft, and evading detention.
Green is currently in Harris County jail for her latest charges, held on an $800k bond.
Even though Miller said she is not aware of any issues of identity theft related to her two sons, she opened an investigation with New York Life.
Miller alleges the funeral home charged her son's policy double the amount she had approved on one of the invoices for Markeveon's funeral expenses.
Investigators with the life insurance company confirmed their findings in an email to Miller.
The email says the handwriting on the document submitted to the life insurance company to increase the payment didn't match Miller's, but it did match the handwriting on a past receipt she received from the funeral home.
They also determined the name on the submitted receipt did not appear to be Unique Green and said the name is illegible, according to the email.
"I don't care if it was fifty cents, a dollar, $100 - that was something that was supposed to be towards me and my daughters to help close out his final businesses or final debts," Miller said.
The life insurance company confirmed they are aware of an issue with Miller's son's life insurance policy, but are unable to comment.
Miller said she has been in touch with Houston police about the investigation into her son's policy.
She said Green gave her most of the additional money that she did not authorize the funeral home to charge to her son's life insurance policy. New York Life has also reimbursed her, she said.
Months before Green's arrest this week, 13 Investigates asked her about Miller's concerns. Green said she denies any wrongdoing and is confident the full facts will demonstrate that she acted lawfully and appropriately at all times.
