Two grand jury indictments issued this week in Gwinnett County highlight the problem —- and potential consequences —- of young men bringing weapons to school.

In the most recent of the two incidents, three men are accused of stashing marijuana, a baseball bat, three knives and a set of brass knuckles in a vehicle parked near the field house at Central Gwinnett High School on April 18. Police said the men went to campus to confront a student.

Josh Bivens, 19, of Grayson; Abraham Hare, 19, of Decatur; and Zacharay Richardson, 18, of Lawrenceville, are charged with carrying weapons within school safety zones, disrupting public school and possession of less than an ounce of marijuana.

Bivens and Richardson have each been released from jail on $4,700 bond. Hare remains behind bars because the arrest violated the terms of his probation on an unrelated case.

The second incident involving weapons on school property arose from an Oct. 16 bathroom brawl at Berkmar High School in Lilburn.

Breiner A. Martinez-Londono, 18, of Lawrenceville is accused of stabbing Efrain Ruiz, who was then 18, in the chest and abdomen with a pocketknife. Ruiz suffered nonlife-threatening injuries.

Martinez-Londono was indicted Wednesday on charges of aggravated assault and carrying a weapon on school property. He has been out of jail since November on $10,300 bond.

Jorge Quintana, spokesman for Gwinnett County Public Schools, said students and visitors who bring weapons to school will be subject to criminal charges and disciplinary action.

"A school is a place for students to come and learn and for teachers to teach," Quintana said. "Any time that there is a report of a weapon on campus, our administrators and school resource officers will investigate and take the appropriate action."
