A former Hueytown principal and longtime educator charged with having sex with a male student is back in Jefferson County amid an investigation that is ongoing.

Brett Kirkham, the 39-year-old human resources director for the Jefferson County Schools, was booked into the Jefferson County Jail at 11:20 a.m. today after being transferred from the Tuscaloosa County Jail where he has been held since in Thursday arrest.

Kirkham, who was placed on leave earlier this month, is charged in Jefferson County with one count of a school employee engaging in a sex act with a student and in Tuscaloosa County on once count of a school employee engaging in a sex act with a student and with possession of child pornography. A Jefferson County judge today set Kirkham's bond at $500,000.

According to court records made public this morning, Kirkham met with the victim on numerous occasions between Jan. 1, 2014 and Jan. 1, 2016 for the purpose of engaging in sex acts. "The victim said they would meet at various locations throughout Hueytown," Hueytown Sgt. Mark Didcoct wrote in the arrest warrant affidavit. "The suspect was also the victim's former principal at Hueytown Middle School."

In the Tuscaloosa County case, which involves the same victim, the arrest warrant says Kirkham did "engage in anal sex with minor between the ages of 16 -18" between Jan. 1, 2013 through Jan. 1, 2016. During those same years, according to the warrant, Kirkham possessed obscene matter "containing a visual depiction of a person under the age of 17 years engaged in any act of sad-masochistic abuse, sexual intercourse, sexual excitement, masturbation, genital nudity or other sexual conduct." Specifically, the records show, Kirkham had a photos of a male under the age of 17 "completely nude showing his genital area."

Bill Veitch, District Attorney in Jefferson County's Bessemer Cutoff Division, announced Kirkham's arrest on Thursday, saying the evidence against Kirkham was "damning," and that he was "most likely" a serial child predator. "It's frustrating. I can prosecute cases and we can put people in prison, but I can't undo if you steal someone's innocence from them,'' Veitch said. "I feel really frustrated and angry. I feel such compassion for the families involved in this."

The victim is no longer a juvenile, but is still in his teens. Veitch said authorities immediately started receiving additional calls about Kirkham shortly after announcing his arrest on Tuesday.

Jefferson County school officials have not commented since the arrest, and referred all questions to law enforcement. Court records don't yet list an attorney for Kirkham.

Kirkham began his teaching career at Hueytown High School in 2000, where he taught for three years. He then took a position at Pittman Junior High in Hueytown in 2004 and worked in that job for two years and two months. He later became the principal of the school, renamed Hueytown Middle School, and served as the school leader for eight years.

In 2012, Kirkham became the school group director/area superintendent for the board of education. His next assignment was as director of assistance and safety for the board and was then named human resources director two years ago.
