Gina Stallis and her sons Sam, 9, left, and Ben, 7, right, were in the house. Gina had just been released from the hospital were she had been treated for symptoms from stomach cancer, a disease she's been successfully fighting most of her life. It was a fluke that she slept over at her grandmother's house that fateful night.
Gina was forced at gunpoint to carry a heavy TV down this steep flight of stairs. The gunmen kept yelling obscenities and threatening everyone to be quiet or they'd be shot.
Police mark the spots where the gunmen forced Isabella and Nick to line up in the hallway. They believed the intruders were going to herd everyone into the basement and execute them.
