Hungary's National Bureau of Investigation detains an unnamed 30-year-old man in Budapest after searches at his flat and at a hospital recover skulls, a lower leg, a hand, a reconstructed face and a heart preserved in a jar.The man, employed as a hospital orderly, admits collecting body parts and to preparing and eating food from them; police say he has a history of dissecting animals and likely obtained remains through his job and by exhuming graves in abandoned cemeteries in Hungary and in Slovakia.Authorities seize computers, phones and other electronic media and hand remains to forensic specialists for DNA and pathology tests that will determine whether the heart is human and whether prosecutors should widen charges beyond illegal use of human bodies.
