Officials say a white supremacist who went on a shooting rampage inside a Sikh temple before being killed by law enforcement was an Army veteran who likely mistook the Sikhs for Muslims.

A shooting at a Sikh temple near Milwaukee left  seven dead on Sunday, including the gunman. According to police reports, a gunman arrived outside the temple at around 10 AM and shot and killed two people. Afterward,  the shooter walked inside the temple and fatally shot four others.
