Manning's father remarried in 2000, the same year as his divorce.
His new wife, also named Susan, had a son from a previous relationship.
Assigned in 2009 to an Army unit in Iraq as an intelligence analyst, Manning had access to classified databases.
In early 2010, she leaked classified information to Wiki Leaks and confided this to Adrian Lamo, an online acquaintance.
The friend also said that Manning's home life was not good and that her father was very controlling. She and her mother Susan moved out of the house to a rented apartment in Crescent, Oklahoma.
Susan's instability continued, and in 1998 she attempted suicide; Manning's sister drove their mother to the hospital, with the 11-year-old Manning sitting in the back of the car trying to make sure their mother was still breathing.
After their move near Crescent, Oklahoma, they bought a two-story house with an above-ground swimming pool and 5 acres (2 hectares) of land, where they kept pigs and chickens.Casey became Manning's principal caregiver, waking at night to make a bottle for the baby.The court heard that Manning was fed only milk and baby food until the age of two.The material was published by Wiki Leaks and its media partners between April 2010 and April 2011.Manning was charged with 22 offenses, including aiding the enemy, which was the most serious charge and could have resulted in a death sentence.
