(AP) -- A judge in Oregon caught a juror texting during an armed-robbery trial when he noticed an unexpected glow on the juror's chest while the courtroom lights were dimmed.
Marion County Circuit Judge Dennis Graves cleared the courtroom and excused all jurors except 26-year-old Benjamin Kohler.
According to a news release from the Marion County Sheriff's Office, Kohler had no explanation for his actions.
Jurors in Oregon are given explicit instructions at the outset of each trial not to use cellphones in court.
Graves held Kohler in contempt, and Kohler spent most of Tuesday and Wednesday in the county jail. He was released Wednesday night.
Neither the nature of the text message nor its recipient was disclosed.
