Authorities say a northern Indiana woman whose infant son suffered frostbite so severe one of his legs had to be partially amputated has been charged with felony neglect. Thirty-three-year-old Brittney Dickens, of Elkhart, was charged Thursday with one count of neglect of a dependent resulting in serious injury. The Elkhart Truth reported Saturday that police were called to an Elkhart hospital in December after Dickens brought her infant son to its emergency room with frostbite and a host of potentially life-threatening ailments. Police say the boy had severe frostbite on his right foot and a severe infection that required the amputation of his right leg below the knee.
