The confusing conflicts that plagued Travis Alexander's life before his gruesome death in 2008 were the topic of Thursday's testimony during day 45 of the Jodi Arias murder trial in Phoeniz, Ariz.

Yet again, domestic violence expert Alyce LaViolette was back on the witness stand. But this time she was fielding questions from the jury, rather than her courtroom nemesis, prosecutor Juan Martinez.

"He was leading a double life," LaViolette testified, as she revealed how Alexander, who died at age 28, lied about his virginity in church, because he had a "significant amount" to lose if the truth about his relationship with Arias, 32, came out.
