Investigation continues in murder of Florida couple

Officials in Florida say they have arrested all of the people they believe were at the scene of the murder of a wealthy couple with 16 children, but they're still gathering information -- especially about someone who wasn't there. The Escambia County Sheriff showed a photo of someone he repeatedly described as a "person of interest." Officials questioned 47-year-old Pamela Long two days ago, but now they can't find her. The sheriff says she is a real estate agent who rented a property to one of the suspects. They are also looking for another person of interest who may be able to fill what the sheriff called a "gaping hole." Why was the security system not turned off in an otherwise well-planned and executed break-in?
