A man who police warn has exhibited "violent behavior" escaped from a Virginia mental health facility Monday triggering a comprehensive search.
Michael Marshall, 33, was reported missing from the Northern Virginia Mental Health Institute in Falls Church Monday evening, Fox 5 reports.
Investigator urged people who see Marshall not to approach him, but to call police instead. They say he's roughly 5 feet 8 inches tall and weighs 235 pounds, with black hair and glasses.
Marshall could be in the areas of Annandale or Falls Church but also has ties to nearby Centreville and Sterling, investigators add.
Falls Church is about 8 miles west of Washington, DC.
