All four turned themselves in at the Juvenile Assessment Center Wednesday night, and Thursday morning made their first appearance before a judge.
Two liter bottles filled with explosive chemicals were tucked into mailboxes in Killearn and Piney Z. Investigators say it was all the work of teens looking for a laugh.
"It initially started as an April Fool's Day prank. And after that? It just kept going after that because apparently it became fun to them."
Now four teens are under arrest. All are students at Lincoln High, and one is even suspected of planting a bomb on his own street.
Justin Terry, Brian Warner, Jeffrey Wilson and Bryce Harris face felony charges for making a destructive device.
"They'll do damage to the mailbox itself; they can pretty much take the top half off and basically, [cause] displacement up to about 20 feet."
There were a total of 10 bottle bombs reported. Luckily no one was hurt, and lucky for the teens, they'll be charged as juveniles instead of having this dangerous "prank" on their permanent record.
The superintendent says the teens could also be suspended or expelled from school.
Leon County Sheriff's deputies, Tallahassee Police and U.S. postal inspectors all worked together to crack this case.
