Authorities confirmed Monday that a Glen Rose sixth-grader was being investigated for allegedly making a terroristic threat to a fellow student.

The 12-year-old allegedly wrote a threatening note and dropped it in the locker of a classmate. The note, which allegedly  included a shooting threat, was then turned over to authorities, who launched an investigation.

The accused’s mother said her child has already served 18 days in an alternative school for allegedly writing the note.

Glen Rose Independent School District Superintendent Wayne Rotan said the district could not comment on student discipline.

“Our discipline would have been in accordance with the student code of conduct,” Rotan said.

The case has been referred to County Judge Ron Hankins for prosecution, which the Somervell County Sheriff’s Department said is standard practice.

“We refer all cases of this nature to the juvenile probation department and the county attorney’s office,” Chief Deputy Darrell McCravey said.

County Attorney Ron Hankins said it would be inappropriate for him to comment on the case because it is still under investigation.

The family is planning on fighting any charges that may be filed and has hired Stephenville-based attorney Shay Isham.
