An Ottumwa man who was arrested for assault last week is now facing drug charges.  You’ll remember 34-year-old Carlos Mendez was arrested and charged with aggravated assault after he allegedly threatened a woman with a handgun in an alley.  Ottumwa Police went on to execute search warrants on Mendez’s apartment and a vehicle.  Those searches turned up controlled substances, items consistent with drug dealing and over $18,000 in cash.  Mendez is now charged with possession with intent to deliver a controlled substance, possession with intent to deliver less than 5 grams of meth and failure to have a drug tax stamp.
