Biography
She also suffered from Bipolar Disorder which impacted her ability to raise her children. She once nearly killed Elliot during a manic phase which caused Elliot to erase his childhood and maintain little contact with his mother. Elliot visited her again after Kathleen was arrested on burglary charges. Bernadette had a psychotic meltdown during his visit on the beach by her house when Elliot brought up his troubled childhood and how his mother tried to kill him. This infuriated Elliot but he left peacefully. Later Detective Benson reached out to Bernadette, who told her about Elliot's troubled childhood. Benson took Bernadette to meet Kathleen in prison. Bernadette encouraged and convinced Kathleen to get help, and the charges against Kathleen were dropped.
