After Felicia Marie-Nicole Smith set baby Levi Cole Ellerbe on fire, she left him and went to work at IHOP, according to the indictment against her.

Smith is facing a first-degree murder charge in the July 18 death of the infant, who was just days from turning 7 months old. She was indicted Aug. 30 by a Natchitoches Parish grand jury.

Natchitoches Parish District Attorney Billy Joe Harrington said at the time of the indictment that the investigation remains active.

The indictment contains some previously unreleased details in the case. Among other documents filed Wednesday with the Natchitoches Parish Clerk of Court's Office is an order with a handwritten note that states Smith reportedly confessed.

The indictment reads that Smith took Levi from the Mayberry Trailer Park home of his mother, Hanna Nicole Barker, around 9:10 p.m. on July 17. She left the park in the 5600 block of the La. Highway 1 Bypass and took the boy about a mile away, to the 700 block of Myrtle Street.

It states that Smith poured gasoline on the baby and set him on fire. Then she went to work just before 10 p.m., it reads.

A call about the fire was received by the Natchitoches Fire Department around 10:25 p.m. It was made by a woman, Kanika Johnson, who saw it as she was driving to her Breda Avenue home.

The fire was spotted from the opposite side of an elevated railroad track, and Johnson said she thought some kids might have set it. She didn't find out what had happened until the next morning.

Firefighters found Levi lying on his stomach in the fire, reads the indictment.

The baby was rushed to Natchitoches Regional Medical Center with second- and third-degree burns over approximately 90 percent of his body. He later was transferred to Louisiana State University Hospital in Shreveport but died around 3:35 a.m. July 18.

The gag order was issued July 30 by 10th Judicial District Court Judge Desiree Dyess.

It was issued "to prohibit any such dissemination of information as law enforcement has made a number of statements in the recent past," it reads.

The order cites a radio interview that State Fire Marshal Butch Browning gave a few days before. Browning discussed the case with Shreveport station, 710 KEEL News, saying that more arrests could be expected and that Smith knew Levi's family.

"This individual had a relationship with the family and certainly had access to the child, so we're still vetting through those things," said Browning during the interview, which was published to YouTube. "It wasn't a random act, which is important for us to put out."

Two other orders were issued by Dyess on July 30. One order set bond on a charge of criminal conspiracy at $1 million and ordered Smith to not have any contact with Levi's father or his family.

The other order denied bond on the first-degree murder charge and ordered Smith to have no contact with either of Levi's parents of their families.

A written note in that order, detailing reasons why bond was denied, states that Smith reportedly confessed.

Barker also has been arrested in the case, charged with being a principal to first-degree murder. The grand jury returned a pretermitted bill in her case, which means it requested more information to consider even as the investigation continues.

An arraignment date for Smith hasn't been set yet, according to court records.

Both women remain in jail. Smith is being held in Richland Parish, while Barker is in Caddo Parish.
