Ackerson's remains were found in Oyster Creek near Skinner Lane in Richmond, Texas in July. Identification was made through dental records days later. The 27-year-old was reported missing on July 18.
Raleigh police have arrested and charged the father of Ackerson's two sons, 32-year-old Grant Ruffin Hayes, and his wife, 39-year-old Amanda Perry Hayes with murder in connection with Ackerson's death.
Texas deputies say they believe Ackerson was killed in North Carolina, and then dismembered, before her body was taken to Texas in coolers. The creek where the remains were found is near Amanda Hayes's sister's home.
Ackerson and Hayes had been involved in a custody battle over their children for more than a year. Hayes was granted primary custody in 2010.
Ackerson's brother told ABC11 Tuesday that police aren't telling him much about the investigation and he's comfortable with that.
"They don't want evidence getting out. And, you know, that's smart on their end. I'm glad they're doing it that way," offered Jason Ackerson.
"Anything that they can use to, you know, put these people either behind bars for life or in the death row," he continued.
