Jon Hammar, a former Marine held in Mexico on gun charges, has been in a Mexican prison for four months on what is being called a trumped-up federal weapon charge. He was arrested Aug. 13 in Matamoros after he declared to Mexican customs agents a shotgun he planned to use for hunting in Costa Rica. He’s been held in jail since August and chained to a bed.
Jon Hammar survived wars in Iraq and Afghanistan. He is now up in a prison in Mexico. (CBS)
