Family members were hoping for more answers from law enforcement regarding the cause of death for Brian Laundrie.

Federal investigators have so far not found evidence that clears the high bar for federal hate crime charges against a man who has been accused of killing eight people at three Atlanta-area massage businesses, two law enforcement officials told The Associated Press.

Amber Kyzer dabbed tears from her eyes for most of her testimony Monday and sobbed at the death penalty trial of her ex-husband, charged with killing their five young children. But then a prosecutor asked her to read a letter she wrote the oldest child, trying to comfort her over the divorce and the pain of suddenly being in a broken home. "You kids are my world and Mommy and Daddy were really blessed to have you," Kyzer said, pausing, then burying her head in her hands on the witness stand and breaking into heaving sobs.
