Brewer said that after Arias began to change, he made arrangements to move closer to his son from his first marriage, and he and Arias broke up.
They kept in touch with occasional phone calls until Arias asked to borrow the gas cans in June 2008, and then called him a week after borrowing the cans to say that her friend had been killed.
Martinez, reading notes from an interview Brewer gave to authorities during the investigation into Alexander's death, asked if Arias had ever mentioned needing an "alibi." Brewer said he did not recall any conversation about alibis.
"After this date of June 4, 2008," Martinez asked, "you received a call from Jodi Arias, and she was very agitated?"
"She was sad," Brewer said.
"Did she tell you that her friend had been killed and she did not have an alibi?"
"I don't remember that," Brewer said.
Arias was arrested a month after Alexander was found dead, in July 2008.
