Tragedy strikes Wisconsin as gunman opens fire at day spa

Employees and customers wait in the parking lot outside Azana Spa in Brookfield.

In August, six people were killed in a rampage at a Sikh temple in another suburb of Milwaukee, Oak Creek. The gunman in that incident killed himself.

Also, just down the road, less than a mile away, is the Sheraton Hotel where seven people were killed and four more wounded at a shooting in 2005. The shooter then, too, committed suicide.
