Gunman kills six in house-party massacre

THE private party following a “zombie rave” was winding down when a man walked out, returned to the house wearing bandoliers of shotgun shells and opened fire on the young crowd.

Six people were killed and another was critically injured as he fired dozens of rounds, police said. Outside, he fatally shot himself when confronted by police.

Police said it appeared to be Seattle's worst mass killing since 1983's Wah Mee massacre, when 13 died in an attack at a gambling club.
