The researchers found that the areas
of the brain that lit up in response to the grossest pictures — like
mutilated bodies and burn
victims — depended on whether the participant was more liberal or more conservative, based on a survey
of political beliefs.

mutilated body of a fourth
victim is found in one
of the city's most expensive hotels, Nergui, the former head
of the Serious Crimes squad, is no closer to catching the killer and will accept any help he can get.
