A Central High School student who was arrested Wednesday with a hunting knife told authorities he frequently took the weapon with him to school and his classes, according to an arrest affidavit.

Justin T. Hammock, 18, Clifton, said he had not been threatened by anybody at the school. However, according to the affidavit, he told a Mesa County deputy sheriff, “You never know who’s out there.”

The deputy was called just before 1 p.m. Wednesday to an assistant principal’s office at Central High, where Hammock and two other students had been detained for allegedly smoking marijuana during their lunch break at nearby Long Family Memorial Park, the affidavit said.

Hammock agreed to let the deputy search his backpack, and the deputy found an 8-inch hunting knife, one blade serrated and the other straight, which was covered in a nylon sheath, the affidavit said.

Hammock was booked into the Mesa County Jail on suspicion of felony possession of a concealed weapon on school property and a petty offense of public use of less than an ounce of marijuana.

He was released Thursday afternoon after posting a $1,000 personal recognizance bond.
