Prosecutors argue that Christiansen and Hubbard had a relationship during their time together in Beverly Hills. Prosecutors wouldn't specify the nature of their relationship, but contend that it continued after Hubbard became superintendent at Newport-Mesa in July 2006.
Hundreds of pages of e-mails dated between 2005 and 2008, and sent mostly while Hubbard was with Newport-Mesa, show that he and Christiansen exchanged messages ranging from affectionate to risqué. Solorzano will review the copies of the e-mails and consider if those messages offer any motive for Hubbard favoring Christiansen.
Ciulla has said the e-mails were "tongue in cheek."
On Thursday, prosecutors mostly focused on Christiansen. She is accused of using the trust of Beverly Hills district officials to convince them to sign off on construction deals with Johnson Controls Inc. Shortly after the district signed a deal with Johnson Controls, the company signed a contract to work with Christiansen's own energy company on the job — meaning that she benefitted from her own recommendation, according to prosecutors.
