(Portland, OR) -- Portland's firefighters union is blasting Multnomah County over an ambulance shortage that resulted in a stabbing victim being transported to the hospital in the back of a police car. Portland Firefighters Association President Isaac McLennan called the situation "infuriating" and "frustrating." McLennan says the union has been calling for action regarding the county's lack of ambulances for years. Officials tell KGW-TV, the number of calls designated "Level Zero" skyrocketed to nearly 15-hundred last year, resulting in fines of more than half-a-million dollars for the company that provides ambulance service to the area. Meanwhile, the stabbing victim eventually reached the hospital and was in critical condition as of late Sunday.
