Sikh Temple Shooter Had 'Personality Change' Wade Michael Page death officially ruled suicide By Rob Quinn, Newser Staff Posted Aug 29, 2012 2:09 AM CDT Updated Aug 29, 2012 2:21 AM CDT 4 comments Comments Wade Michael Page exhibited bizarre behavior in year before shootings, sisters tells officials. (AP Photo/FBI, File) (Newser) – The white supremacist who killed six Sikh worshipers at a temple in Wisconsin had a major personality change in the year before the shooting, according to a newly released investigative report. Wade Michael Page's sister told investigators that he had become more intense, lost his sense of humor, and had become bloated, probably due to drinking. The county medical examiner's official report confirms that Page, who had been shot in the belly by responding officers, died of a self-inflicted shot to the head, reports Reuters. Toxicology reports are still pending, but the police chief whose officers responded to the shooting says it would be an "excuse" to blame alcohol for the mass shooting. "He has those thoughts, and they're there. The alcohol didn't cause that," the chief tells AP. A police officer Page ambushed and shot nine times at close range was released from a local hospital last week.
