Child, 9, calls police after finding parents shot dead

HOUSTON (AP) -- Authorities say a 9-year-old girl called police after she found her parents dead inside their southwest Houston home.

Officers who responded also found the couple had 6-month-old triplets.  None of the children have been hurt.

Police are investigating the case as a murder-suicide. Names of the man and woman haven't been released.  The 9-year-old told police she heard her mother and stepfather arguing Saturday, then heard two gunshots.

Child welfare officials have released the children to relatives.
