A Texas high school volleyball coach allegedly fondled a student-athlete in her car after track events — and waited until she turned 18 before having sex, according to court documents. 

BreAnn Halcumb, 34, was “hip to hip” with the senior for three months before they first had sex — and she shamelessly tried to blame the student when confronted by the girl’s alarmed parents, according to an affidavit seen by KLTV. 

Halcumb’s now-former colleagues at Randolph High School reported the coach to the authorities last month after spotting signs of “suspicious activity” involving the coach and girl.

Halcumb and the girl messaged 160 messages on a school forum between February and April, with school officials describing it as “teenage flirting” in breach of its policy, according to the affidavit.

The last message was sent on April 24, and it included the staffer’s personal phone number.

Halcumb waited for the student to turn 18 on April 30 before having sex on at least two occasions.

Halcumb allegedly fondled the student in her car at a park en route home from a track meet on May 14 where she made a “wrong turn.” 

The coach would also go to the student’s home for so-called “nail services” where they had sexual contact, according to the affidavit.

Halcumb allegedly ordered the teen not to tell anyone about their fling — and the student believed the feelings were serious.

The teen also told cops she and Halcumb kissed twice. 

Halcumb, who faces a maximum of 20 years in prison, was confronted over her behavior by the girl’s dad on a speakerphone call as he wanted to “understand her perspective” — and she allegedly ‘fessed up and said her behavior was wrong, according to the documents.

She was asked why she didn’t report the situation to school officials, but was unable to give a reason.

During the call, she shamelessly tried to blame the young student by claiming the teen tried to initiate the first kiss.

Halcumb told cops the teen “pushed up on her and tried to kiss her first,” according to court records.

Halcumb left her role at Randolph High School before being arrested.

She had recently taken a new volleyball coaching job at Cedar Creek High School, located in the Bastrop Independent School District.

Officials are “reviewing the matter in accordance with district policies,” executive director of communications Evan Moilan told KSAT.

“The safety of our students, staff, and community is always our highest priority,” Moilan said.
