Former Randolph High School volleyball coach Breann Halcumb was arrested after investigators said she developed an improper relationship with a student athlete. According to Bexar County deputies, messages uncovered during the probe pointed to an intimate relationship, although investigators reported finding no evidence of sexual contact. Halcumb was taken into custody in Panola County and later transferred to the Bexar County Sheriff’s Office.
Deputies said the investigation began after a school administrator was alerted by the student's parents. Investigators then reviewed messages that officials say showed an intimate relationship and appeared to show Halcumb coaching the student on what to say. Authorities told reporters that the contacts took place outside regular school hours, including at school events, and that Halcumb urged the student not to talk about the relationship. These details were reported by WOAI.
School records show she led the program
Halcumb is listed as the Ro-Hawks' head varsity volleyball coach on the district’s athletics pages, according to Randolph Secondary Schools. The sports site MaxPreps shows her as the team's head coach for the 2025–26 season. The district told WOAI it became aware of the allegations during the 2025–2026 school year and that Halcumb resigned and is no longer employed by Randolph Field ISD.
Legal context
Texas law criminalizes improper relationships between educators and students under Texas Penal Code §21.12, an offense prosecutors typically treat as a second-degree felony. Legal guides note that the statute bars sexual contact between school employees and enrolled students and that electronic communications and grooming behavior can factor into charging decisions. Bexar County officials told WOAI that while messages revealed an intimate relationship, investigators found no evidence of sexual conduct.
What happens next
Cases like this are typically reviewed by a county prosecutor to determine whether formal charges will be filed. Reporting so far has not listed any court filings tied to this matter. Randolph Field ISD’s online pages now list Halcumb as the former coach, and the district has stated she is no longer employed while the investigation continues.
