I don't know the name of the song nor who sings it but I do remember elements from the video:
-Couple in car getting ready to rob a house
-Put masks on
-Starts robbing house
-Owner of house hears couple in house, grabs a gun and searches for them
-Owner runs into boyfriend and shoots him
-Girlfriend runs up to him crying and takes her mask off looks at owner and runs off
-Girl had short curly hair
-Song was possibly about love
