WALLA WALLA -- A Superior Court jury has determined that a man who assaulted a girl here in the late 1960s with the intent to rape her is a sexually violent predator. The verdict in the civil commitment case against Calvin J. Mines was reached Tuesday afternoon at the end of a seven-day trial. The six-woman six-man jury deliberated about an hour-and-15-minutes before reaching its unanimous decision. The verdict means Mines will be locked up indefinitely until he no longer is a danger to society.
