A family of four were found shot dead in their home near Geneva on Friday in what Swiss police suspect was a domestic incident.
Officers discovered a 52-year-old man and his 47-year-old wife along with their sons, ages 16 and 19, in an apartment in the suburb of Carouge. Neighbors had alerted the authorities after becoming concerned about the family's whereabouts.
A handgun was found inside the apartment, police said. Police declined to provide further information on the victims' identities except to say they were from Geneva.
Switzerland has a high rate of firearms-related deaths, blamed by critics on the wide availability of guns and rifles. The Alpine country has a militia army and comparatively loose gun control laws.
