A box of loaded guns were found at a Parkland, Florida school Thursday, several miles away from the site of the Marjorie Stoneman Douglas mass shooting, reports said.

The weapons belonged to Somerset Academy Principal Geyler Castro, officials at the charter school told parents in a Friday letter, according to WPLG-TV.

Castro brought a closed box containing two firearms into the school; they were found unattended by officials in a locked room, the station reported.
