The Latest on escapes from a Washington mental hospital (all times local):

3:30 p.m.

A review of records now shows that at least eight patients from Washington state's largest mental hospital committed assaults or other offenses when they escaped or walked away from the facility in the past 3½ years.

When a man accused of torturing a woman to death broke out of Western State Hospital with another patient in early April, officials called it a rare occurrence and cited only two other escapes in the past seven years.

But a review of police reports and interviews by The Associated Press reveal 185 instances in which patients escaped or walked away in just the past 3 1/2 years. Records released to AP through Thursday show eight individuals committed assaults or other offenses while out.

State spokeswoman Kathy Spears says escapes from inside the hospital are "extremely rare." She says most reports to local police involve patients who don't return after being allowed to leave hospital grounds for a short time.
