Wade Michael Page, the man who killed six members of the Aug. 5, died of a suicide, according to the Milwaukee County medical examiner's office.
An Oak Creek police officer shot Page in the stomach shortly after Page opened fire on police . Officials initially said Page was killed by that officer, but three days later that after the officer shot him, Page shot himself in the head.
The medical examiner's report also includes comments from Page's sister, according to the Associated Press. She talked about Page's history of alcohol problems and how his demeanor changed over the past year.
The FBI is still investigating Page and have not determined a motive.
