Miami-Dade jailers were stunned when they found a gun in the shoe of inmate Santos Mejia as they were booking him this week.
The .22-caliber handgun was taken from Mejia and given to Miami officers. Mejia was being booked on charges of aggravated assault with a firearm and aggravated battery with a firearm. An additional charge of bringing contraband into a jail was filed against him for possession of the .22 in his shoe.
Miami police are investigating why veteran patrol officer Emilio Valenzuela failed to find the gun before turning Mejia over to the jailers.
