Misty Cook, the 31-year-old ex-girlfriend of Wisconsin temple shooter Wade Michael Page, was arrested Sunday on suspicion of being a felon in possession of a firearm.

Reports are the gun was found at her home in the 1400 Block of Marquette Avenue in South Milwaukee.

South Milwaukee Police Chief Ann Wellens confirmed Cook was arrested Sunday and said the Milwaukee County District Attorney's Office will later bring charges.

Police believe Cook isn't linked to the shooting at the Sikh temple that left six people dead. Her ex-boyfriend Page, a white supremacist, was suspected of the killing. The FBI told the media that Page died from a self-inflicted gunshot wound; early reports indicated he had been killed by police bullets.  

Here's what we know about Cook from other reports:

- She rented a place with Page in February and continued living with him until the relationship went sour in June. Page then moved to a duplex in Cudahy;

- She shares Page's white-supremacy beliefs;

- She is a nursing student and waitress;

- She was convicted in 2005 for fleeing and eluding police. Therefore, as a convicted felon, she cannot own firearms.
