Prosecutors in the upcoming trial of three jail guards charged with fatally beating mentally ill inmate Michael Tyree and assaulting another inmate want to introduce text messages that they claim show the guards were motivated by their general contempt of prisoners, and the pleasure they took in seeing them suffer. “This motive is illustrated in the texts found on their phones wherein they express humor and enjoyment at pain or discomfort experienced by the inmates, regardless of who inflicts it,” Braker wrote.
