(Portland, OR) -- Residents in east Multnomah County say they're tired of finding bags of human waste left along roads. Since 2018, more than 500 bags have been found. It's illegal to leave the waste and county code enforcement officials want to find the person or people responsible. Residents say they don't want to clean up after the perennial poopers. The county's code enforcement division is asking anyone with tips that can identify the person to contact them.
