Sunset Hills, MO (KSDK)-- A murder-suicide investigation is underway in Sunset Hills.
Sunset Hills Police responded to a home on Maclane Court early Sunday morning to find a male and female in their 70's dead in an upstairs bedroom from single gunshot wounds to the head.
Based on evidence gathered at the scene, Sunset Hills Police believe the female resident shot the male, 73 year old Wayne Bales, before turning the gun on herself, 72 year old Monique Martin.
Sunset Hills police chief William LaGrand says the two were meeting friends at the airport to go on a cruise. When they didn't show up the friends called Bales' brother.
He went to their Sunset Hills home and found them dead.
At this time detectives do not believe any other persons are involved.
This is still an active investigation as police try to determine a motive.
