Update from Jeremy’s support website. He has been put in solitary confinement as of October 10th 2014. They believe the actual reason for this is retailitory punishment for making complaints of his mail being held.
Please do not call the prison as his support feels this could make the situation worse.
However, you can still write letters of support to him; let him know we support him on the outside.
