Timothy Lebron Smith, 16, reportedly died Saturday after overdosing on Oxycodone pills stolen from his friend’s grandfather, who suffers from cancer, wsbtv.com reports.

Catoosa County, Ga., Sheriff Phil Summers said Smith had taken four 80 milligram Oxycodone pills given to him Friday by a classmate at Ringgold High School. Three other students reportedly took Oxycodone pills and became ill, wsbtv.com reports.

"Oxycodone is a time-released drug," Sheriff Summers told the Catoosa County News, wsbtv reports. "They were probably uneducated about the drug, took a couple pills and when they felt no effect, they took more. By the time they knew something was wrong, it was too late."

The 15-year-old who stole the pills from his grandfather faces voluntary manslaughter and drug charges, wsbtv.com reports.
