Except for the unimportant differences that this case was tried to the court rather than to a jury, and the mental illness here was of longer duration, it presents identical questions as were decided in State v. Johnson, 67 Wn.2d 671, 409 P.2d 655 (1966).

The judgment is affirmed, there being substantial evidence to support it. State v. Mercy, 55 Wn.2d 530, 532, 348 P.2d 978 (1960).
