(Portland, OR) -- A Portland nurse was found dead while traveling in Hungary. Mackenzie Michalski was a neurosurgery nurse practitioner at Providence St. Vincent Medical Center. She was 31-years-old. She was reported missing on Tuesday when she didn't show up for her return flight to Portland. Police arrested a suspect who's described as an Irish citizen. Investigators say he confessed and showed police where he hid her body. Providence St. Vincent Medical Center released a statement saying "Kenzie" was kind and loving. It describes her as a great friend and a valued caregiver. They say the loss is especially difficult as it follows the death of nurse Melissa Jubane in September.
