Brendon Young, 18, of Lawrenceville, turned himself into the Jacksonville County Sheriff’s Office on Sunday. He was booked into the jail there just after 1 a.m., according to online jail records.
The Gwinnett County Police Department named Young a suspect in the death of 17-year-old DeAndre Henderson.
Police said officers found Henderson shot at around noon Wednesday on Technology Drive about a mile from the high school. He died at a local hospital, according to police.
Investigators believe Henderson left the Norcross campus during school hours and was shot off-campus. Police called the shooting an isolated incident.
Investigators have not disclosed what led them to name Young as a suspect.
More charges are possible, police say, as the investigation continues.
