Barre said he did not hear anything further from FBI agents until his son was arrested.
Barre described Mohamud's life in the strict Muslim home as troubled by the time he came to the FBI's attention. Barre and his wife, Miriam Hassan, had split up, and the couple's daughter — Mohamud's younger sister — kept running away.
Mohamud was a sweet-natured kid, Barre testified, but impressionable and immature. The family believed Barre's contact with the FBI led to Mohamud being placed on the no-fly list.
Mohamud turned from an engaged, sociable freshman at Oregon State University into a withdrawn sophomore who slept during the day, Mohamud's friend Mohammad Mohamed testified.
Barre, under cross-examination, told Knight he drilled into his children that they should be grateful to live in America. He said he told them not to make waves, to make their parents proud.
"Did you do everything you could to help your son?" Knight asked. "Did you give him every chance to succeed?"
With his wife sitting 20 feet away in the gallery, her chin cradled in her right hand, Barre paused.
"I wish I did more."
