Ammie Brothers, 29, of Columbus, Ga., recently pled guilty to unlawfully obtaining personal information from the U.S. Army's Army Knowledge Online system.

Brothers, a sergeant in the U.S. Army, pled guilty to one count of unauthorized access to information from a U.S. Army computer system.

She admitted that she repeatedly accessed two victims' Army Knowledge Online accounts between April 2009 and October 2011, after first calling the Army Knowledge Online helpdesk and providing the victims' birthdates and Social Security numbers in order to obtain temporary passwords.

When Brothers' home was searched, law enforcement officers found documents printed from Army Knowledge Online, including victims' Social Security numbers, bank account numbers and employment history.

Brothers admitted that she also harassed the victims by telephone, accessed their credit card accounts, and authorized a charge to one of the victims' cards.

Brothers will be sentenced on October 24, 2013. She faces up to five years in prison.
