Martial Simon, a schizophrenic man accused of fatally shoving Michelle Go in front of a subway train in January, will be sent to a locked psychiatric facility indefinitely, after prosecutors agreed not to contest that he is unfit to stand trial. Simon, 61, was declared unfit by Bellevue Hospital Center psychiatrists according to his lawyer. Simon had been held at Bellevue since his arrest in January. He was charged with second-degree murder in the death of Go, a consultant at Deloitte.
