Wisconsin's history of mass shootings
MILWAUKEE - The rampage at Azana Spa in Brookfield marks the sixth mass shooting in Wisconsin since 2004.
In November 2004, six people were killed when 35-year-old Hmong immigrant Chai Vang shot eight people while deer hunting in northern Wisconsin.
A judge sentenced Vang to life in prison.
Fast forward to March 2005, less than half-a-mile from the Brookfield spa shooting, gunman Terry Michael Ratzman killed seven people and hurt four others at a Living Church of God service inside the Sheraton Hotel. The pastor and the pastor's son were among the victims. Ratzman took his own life.
Two years later in June 2007, six people were killed in Delavan when 23-year-old Ambrosio Analco entered an apartment and shot his own twin infant boys, his estranged wife, her sister and a friend. Analco then shot and killed himself.
Six died and one person was hurt in October 2007 when off-duty Forest County Sheriff's Deputy Tyler James Peterson went on a shooting rampage at his ex-girlfriend's apartment. He killed teenagers who had been his high school friends and classmates.
The 20-year-old Peterson then shot and killed himself.
Then, on a Sunday morning just two months ago, white Supremacist Wade Page opened fire at the Sikh temple in Oak Creek.
Six people were killed there.
In late October, Radcliffe Haughton opened fire on his estranged wife, Zina Haughton, killing her and two other women, and wounding four others before killing himself at the Azana Spa in Brookfield.
