MILWAUKEE (AP) — The FBI's top official in Milwaukee says the arrest of an ex-girlfriend of the gunman who killed six people at a Sikh temple wasn't connected to the slayings.

Agent Teresa Carlson said Wednesday that Misty Cook was arrested on a weapons violation Sunday after investigators interviewed her. But federal officials say Cook is not connected to the shootings, has been cooperative with authorities and was quickly released.

Milwaukee County sheriff's spokeswoman Fran McLaughlin says the 31-year-old Cook also went by Brenda Cook. Online court records show Brenda Cook pleaded no contest in 2005 to a felony charge of fleeing an officer.

Authorities have identified the temple shooter as Wade Michael Page. Neighbors say he and Cook broke up this past spring.
