The message -- which said "gunman be at west hall today" -- was sent to the wrong number around noon, and it wasn't even intended for West Hall Middle and West Hall High schools.
The actual text was "gunna be at west hall today" but the sender's new cellphone changed the spelling of "gunna" to "gunman" and law enforcement was notified, the Gainesville Times reported.
Lockdowns were ordered at both schools as officials investigated and authorities said the person who received the message did the correct thing by reporting it.
"It was a combination of odd circumstances," a Hall County Sheriff's Office spokesman said.
"The school system always relies on law enforcement for school safety and anytime they request a lockdown we go with that request," a Hall County Schools spokesman said. "We always take every precaution concerning a potential threat or danger."
