PORTLAND, Ore. – A man who stole the wedding ring from a victim of May’s knife attack on a MAX train has been sentenced to 13 months in prison.

George Tschaggeny pleaded guilty to first-degree theft, tampering with evidence and identity theft last week.

Police said Tschaggeny was seen on TriMet surveillance video taking a backpack that belonged to Rick Best immediately following the attack. Best was one of three men stabbed May 26 after confronting a passenger who had gone on an anti-Muslim rant. Best died on the train and another victim died at a hospital.

Officers said Tschaggeny was wearing Best's ring when he was arrested. An indictment said Tschaggeny used Best's credit card five times before he was taken into custody.
