Nathaniel Sebastian is accused of killing his mother, Susan Mayo, stuffing her in a metal drum and burying her under the front porch.
That alone is enough to make most murder suspects seem tame in comparison.
Mayo went missing July 17 and was missing 10 days shy of two months before she was found underneath her home where Sebastian buried the drum containing her body.
Sheriff's deputies say that Sebastian has already admitted to the crime, but now Capt. Paul Burch is dropping another bombshell about Sebastian. New information leading them to investigate the possibility there could be another victim over 25 years ago.
Burch tells NBC 15 that a former teacher has come forward to say there was another death in the family, a death the informant says was suspicious.
But clues will be much harder to find this time. What we were told by the person who contacted us, is that it was a young sibling, an infant sibling.
But Burch says it's worth a look, not just because of this tip, but because of the behavior of Sebastian himself.
According to Burch, Sebastian has already admitted to a fascination with Chicago serial killer John Wayne Gacy who buried the bodies of his victims under his house.
In fact, according to Burch, it was that admission from Sebastian that led one of his detectives to suggest looking under the family's front porch where that metal drum containing Susan Mayo's body was found.
He would send quotes and photos of Gacy in the forms of threatening communications to his ex-girlfriend and her parents.
Turns out the discovery of Susan Mayo's body under her front porch is not the first time that law enforcement has been called out to that house in Wilmer. In fact, Burch tells NBC 15 it's happened not once, not twice, but many times before and always the root of the problem he says seemed to be Sebastian.
She was fearful of him and there were physical altercations, some involving weapons.
During the investigation, Sebastian hasn't shied away from the limelight. In fact, says Burch, he seems to be enjoying the attention he's getting from the Sheriff's department.
This leaves Burch and his detectives to wonder, and reporters to ask one very troubling question: Are we looking at a possible serial killer?
