More details are emerging about Sunday’s deadly shooting at a US Sikh temple in the state of Wisconsin. Authorities say 40-year-old Wade Michael Page walked into the temple outside of Milwaukee and opened fire with a handgun that was purchased legally.

Investigators have found out that Page was a former US army soldier and a neo-Nazi who led a racist white supremacist heavy metal band. The FBI says it is still investigating his identity and the motive for his crime. Page was shot dead on Monday by a police officer after he killed one female and five male members of a Sikh congregation. The victims ranged in age from 39 to 84.
