Florida ? The accomplice assigned to turn off surveillance cameras before an elaborate, deadly break-in at a sprawling Florida Panhandle home never did, but the seven people accused in the crime apparently did not know that, authorities said Wednesday.

Melanie and Byrd Billings, known for adopting children with special needs, were shot to death a week ago. An extensive surveillance system captured footage of masked men — some dressed as ninjas — slipping into front and back doors at the home.

The video led investigators to a red van used as a getaway car and eventually to the suspects, a loosely connected group of mostly day laborers who knew each other through a power washing business and an auto detailing operation.

They were in the nine-bedroom house for just four minutes and on the property for 10, Escambia County Sheriff David Morgan said.
