UPDATE: Montgomery County Sheriff Deputies say the mysterious woman seen ringing a doorbell in the Sunrise Ranch neighborhood last week is safe.
They were called to a home around 11 a.m. when a man was threatening to commit suicide. When deputies arrived they found the woman's boyfriend inside the home. He died from a self-inflicted gunshot wound.
