Three children, ages 7, 11 and 16, were in the house when their mother was shot, police said, but it is not known if they witnessed the shooting. The woman's 16-year-old called 911 to report the shooting.
The children are now in the custody of Child Protective Services.
Officers told NBC 5 there have been prior calls to the Fink's home, but no charges or criminal offenses were determined to have occurred regarding these calls.

A hearing was scheduled in the case on Thursday, but court records show it was cancelled.
