SAN FRANCISCO (AFP) - Five children aged between seven and 16 have been found dead at their mobile home south of Seattle after apparently being gunned down by their father, police said. Pierce County Sheriffs spokesman Ed Troyer told reporters Saturday investigators believe the children may have been killed by their father at their home in Graham, about 30 miles outside of Seattle, Washington state. The body of the 35-year-old man was discovered dead earlier in the day in a different part of the state. Police officials believe he committed suicide. Four of the dead children were girls.
