The mailbox bomber won’t be free for a long time. Back in early September doctors who’d examined and interviewed Luke Helder said he’s delusional and incompetent to stand trial. Helder’s accused of putting pipe bombs in rural mailboxes across Illinois, Iowa, Nebraska, Colorado and Texas, back in May 2002. Some of the bombs, which were rigged like booby-traps, went off…and injured four letter carriers and two Iowa women. Helder was arrested after a brief intensive search, and has been held ever since at a federal medical center — a prison hospital, in Rochester, Minnesota. Now a federal magistrate in Minneapolis has ruled that 23-year-old Lucas Helder is mentally ill and should be committed. Civil-rights regulations have made it harder to commit a patient for involuntary care but the judge noted Helder thinks he can leave his body and communicate with the public by mailbox bombings, and ruled he’d likely pose a risk to his own life or safety, or that of others, if he’s released.
