SAN SALVADOR, El Salvador -- A Salvadoran woman is in some trouble after she allegedly tried to smuggle into the country's main prison a military grenade and marijuana hidden in her vagina. The cylinder was about 10 inches long and 4 inches wide. Officials didn't say what prompted them to check Lidia Alvarado, 44, but authorities have raised the security level at jails across the country, fearing inmates may be planning something.
