An Oklahoma man who pleaded guilty in the fatal stabbing of his parents, two brothers and a sister sobbed as he testified in the murder trial of his brother, who is also charged in the attack.
Robert Bever told jurors on Friday that he doesn't know what he was thinking at the time of July 2015 attack. He testified on behalf of the defense in the murder trial of his younger brother, 19-year-old Michael Bever.
Robert Bever is serving life in prison without parole. His brother's attorneys say the elder brother is to blame for the attack.
Michael Bever and jurors also cried during the testimony. The trial was then recessed.
Michael Bever was 16 and Robert Bever was 18 at the time of the attack. Their then-13-year-old sister survived, and a 2-year-old sister was unharmed.
