A Texas teacher is in custody after she allegedly shot her 17-year-old son while driving him to school in a shocking murder that has stunned a community.

As CrimeOnline previously reported, 17-year-old Garrett Hunt was found fatally shot in Reisel, Texas, on Monday morning inside a parked vehicle, with the engine still running. His mother Sarah Hunt, 39, was later arrested when she was found walking back into town, and has been charged with her son’s murder.

The boy’s mother, who is a 5th-grade teacher in nearby Waco, reportedly talked to bystanders about her son’s death shortly after she allegedly shot him. According to an affidavit obtained by KWTX, Sarah Hunt encountered two people in Riesel Square, and said her son needed help.

“What have I done…this is not real,” she told the two people, according to the affidavit. She also said that her son was in her mother in heaven.

The report indicates that Hunt was questioned by police shortly after the incident, during which she was emotional and expressed regret, but also appears to have been somewhat incoherent.

“I didn’t mean to, I didn’t mean to,’” Butler said over and over again, according to the report.

The affidavit also states that Hunt was driving her son to Reisel High School at the time of the fatal shooting, though the report notes that Garrett was not yet enrolled as a student there. As CrimeOnline previously reported, the family moved to the area recently. The report indicates that Garrett’s mother and father live separately, as she had picked up her son at his father’s mobile home Monday morning.

Sources reportedly told the news outlet that Garrett may have been on his way to register and attend his first day of school.

Hunt is reportedly first-year teacher at Lake Air Montessori Magnet School, where she teaches fifth-graders. The Waco Independent School District told KWTX they had not yet been in contact with her, and that they intended to put her on administrative leave with the option of resigning voluntarily. If not, Waco ISD will likely terminate Hunt’s contract, which is probationary at this time.

As CrimeOnline previously reported, Hunt has no previous criminal history.

Police told the news outlet that the murder is still a very active investigation, and that a clear motive remains elusive.

“At this point we don’t have a motive, we don’t know what happened, we don’t know what led up to this, it’s a big mystery, and that’s what we’re trying to determine, what caused this,” McLennan County Sheriff McNamara said. “We just don’t know at this point.”

“It’s a very sad, tragic situation, I don’t know how else to describe it,” he said.

Hunt is in custody on $500,000 bail.

CrimeOnline will provide further updates when more information is available.
