The Brunswick County Sheriff’s Department is currently investigating an incident were a package containing marijuana, tobacco, cellphones, and a USB‑C-to-lightning converter was left outside of a school.

The discovery was made on Monday morning at Brunswick Academy in Lawrenceville.

Authorities say they received a call about a suspicious package around 8:24 a.m. by employees of the school.

After speaking to witnesses, authorities found that the package was flown over to the school around 5:40 a.m. and abandoned:

“During our investigation, it was determined that this package was dropped around 5:40 a.m. due to the fact that the witness saw a drone during that time land on the grounds,” Brunswick County Sheriff Brian Roberts wrote in an email. “Soon thereafter, the witness saw a small dark-colored sedan come into the parking lot of the school and grab the drone.”

While the package was left at the school, authorities say they believe the package was intended for the correctional facility next door:

“Based on our investigation, it is obviously apparent that the package was intended to be dropped at the adjacent property of the Lawrenceville Correctional Center, which is operated by a private company named The GEO Group,” Roberts said. “We have had numerous calls for service at the prison this year to include other drone sightings alleging the same criminal activity.”

The Brunswick County Sheriff’s department says they are still investigating the incident and are attempting to locate the suspect or suspects who attempted to sneak the contraband into the jail.
