Allison and Bertrum Jean leaned over their seats and looked at the floor of the courtroom. Bertrum held his hands over his ears and turned to the wall beside his seat.
After a few minutes, Botham's parents and family and friends got up to leave.
District Judge Tammy Kemp has requested that the footage of the body cameras be played on Wednesday, the third day of the Dallas murder trial.
Bothams parents saw the video on Wednesday for the first time, a family lawyer told CNN, S. Lee Merritt. The jeans did not know that the judge would ask to see the footage, Merritt said.
When Allison and Bertrum Jean left, Kemp found that the family was still in the room.
"I'm so sorry, I did not care about the family of the alleged victim," Kemp said.
Last April, Allison Jean heard the distress call Guyger had dropped after the shootout and felt an anger that surprised her. She could not hear anyone who helped Botham when he lay in his house and died, Jean told CNN in an interview from St. Lucia where she lived and raised Botham.
Guyger seemed more concerned that she lost her job than her son, she said.
Ever since Jean heard the distress call, he was preparing to get through the process and face the murderer of her son. In therapy sessions, she had worked through scenarios that she might encounter in court and ways to deal with them. From August she laid the Saturdays for fasting and prayer free.
Findley and Botham's brother Brandt stayed in the courtroom when the footage was played on Wednesday.
More than an hour later, the jeans returned. Bertrum Jean was still wiping his eyes.
