“The bullet carried with it those fibers,” Pfeifer said.
The jury also heard testimony Friday from Kathy Thomas, a psychologist who works with police and other emergency personnel.
Thomas is a defense witness who was allowed to testify before the prosecution rested its case because of scheduling complications.
Bryan's attorney, Gary James, called Thomas to help explain some of the strange behavior reported by Becky Bryan's friends who were with her after the shooting. One friend testified earlier in the week that Becky Bryan was talking on the phone and laughing while retelling the story of her husband's shooting with graphic details.
Another friend testified that on the way to the hospital after the shooting, Becky Bryan showed her a photo of another man's penis and said she had sex with the man earlier that day.
Thomas said everyone handles traumatic situations differently, and it's not unusual for police, firefighters or their families to use humor in tough situations.
“Sometimes the option is laugh, cry or throw up. Comedy is certainly more appealing,” Thomas said.
On cross examination, Thomas said she could not explain the specific behavior displayed by Becky Bryan after the shooting. Thomas said she has never seen someone laugh when informed of a loved one's death, and talking about having sex with another man in that situation is “bizarre.”
“It seemed to be she wasn't that concerned about her husband,” Thomas said. “It's unusual behavior.”
The trial is scheduled to continue Monday morning.
