A man was sentenced to a month in jail after he threatened a woman with a knife.The defendant, Dustin Cody Hirzel, 26, entered guilty pleas to charges of vandalism and assault. He was directed to serve 30 days of an 11-month, 29-day sentence and must undergo a mental health evaluation. He was originally charged with felony assault but the charge was lowered as part of his plea bargain.The victim said Hirzel entered her Lake Shore Drive home with a knife in his hand and was acting strangely as if he were looking for someone inside the house.“She (the victim) had just returned home from shopping when Mr. Hirzel entered the front of the house with an open knife,” said McMinnville police officer Katelyn Neal.
