"They are going to be apart for a long time," Cohen said. "I think they've got a really strong bond, but it's just so hard… For both of them, family comes first, and they're family. They've been together for years. They're high school sweethearts."
Joe and Teresa were officially married in 2000.
Joe and Teresa will be allowed to serve their time separately, with Teresa going in first. Joe begins his sentence when she exits. This is to allow one of them to watch the couple's four children.
