UPDATE: The man convicted of killing six children in a school bus crash has been indicted in Davidson County on multiple charges of statutory rape.

The Davidson County Grand Jury returned the indictments against Johnthony Walker, 26, on eight counts of aggravated statutory rape and one count of sexual exploitation of a minor.

Walker was arrested in June 2018 at the alleged victim’s house in Davidson County after her parents called the police. The girl was 14 years old at the time of the incident.

In an affidavit, Walker admitted to having sex with the girl while he was staying with the family.

At the time of his arrest, Walker was out on bond while appealing his conviction in the 2016 school bus crash.

During a July 2018 court hearing, a Metro Nashville Police Department sergeant testified that Walker admitted to having sex with the girl five times.

"I asked him how he would characterize the situation ... he said it was concerning at first, that the age bothered him ... he said something to the effect that she's only a child, just a baby to me, and looking back on it, I find it repulsive that this has happened," the sergeant said.

PREVIOUS STORY: A judge said there is enough evidence to send Johnthony Walker's rape case to a grand jury. Thursday afternoon, the former bus driver was in a Nashville courtroom for aggravated statutory rape charges. In June, Davidson County authorities said Walker had sex with a 14-year-old girl while staying in Nashville on bond for the Woodmore bus crash.

According to officers, the family of the 14-year-old became suspicious of a relationship between the teen and Walker. They confronted her, called 911 when the minor admitted it, and according to testimony, Walker confessed.

“Fourteen-year-old victim admitted to having sexual intercourse with a 25 year old male. Which turned out to be the defendant, Mr. Johnthony Walker,” said Metro Nashville Police Department Sergeant David Slessinger.

It was a brief hearing, however new details emerged in court Thursday during Johnthony Walker's preliminary hearing.

Sergeant Slessinger testified about his interview with Walker and the victim's family the night of Walker's most recent arrest.

“I spoke with the family. The victim went on to The National Children's Alliance for a forensic interview. I spoke briefly with the family. My conversation was short because they were visibly upset.”

During the interview, investigators said Walker admitted he was disturbed by their age difference. The teen is 11 years and nine months younger than Walker.

“He said something to the effect of, ‘she is only a child, just a baby to me. Looking back on it, I find it repulsive this has happened.”

Walker admitted to police to having sex with the girl five times, claiming it started in April of this year.

“The only time he was specifically able to say was when the family had gone to the grocery store or the store to do some shopping, and they were left home alone. It took place in what he called the family room.”

Walker wrote a one-page apology letter to the teen while he was in police custody.

“I offered him the opportunity to write an apology letter to the victim. He agreed that was a good idea. He was provided pen and paper, and penned out a page long letter to her.”

The investigators said there are no allegations that force was used. However, the age of consent in Tennessee is 18 years old.

Walker remains in custody on a $350,000 bond.

Earlier this year, Walker was convicted of six counts of negligent vehicular homicide and other charges in connection to the Woodmore bus crash.

A Hamilton County judge sentenced Walker to four years in prison and said he could remain out on bond.

Walker was staying in Nashville while he appealed his case.
