An employee at the Lee County Publix found a .40-caliber handgun with 12 rounds inside on a sink in the men's bathroom.
The employee notified store management who called the Lee County Sheriff's Office. At this time it's not known who left the gun, but authorities are running the serial number through the ATF data base to see if they can figure out how the gun got there.
No one was injured by the weapon.
