Investigators spent the weekend trying to figure out what caused an explosion to level a home in New Jersey -- it's a case that has brought no answers to the family living inside.
Six people were at the house in West Milford the blast rocked neighbors around 9 p.m. Friday. Five of those inside had to be flown to hospital.
Home surveillance camera managed to capture the deafening boom from the Banker Street home no longer standing. Neighbors wondered whether the noise came from a lightning strike, until they heard screams for help and saw the flattened home and debris scattered across the street.
Just as mysterious as the cause is how the family inside managed to survive.
"I don't know, I hear my husband burned," Quinn Pham told News 4. I talked with my husband, he's okay now."
In addition to her husband, his father and three friends were injured in the blast. The family says they were getting the home ready to move-in prior to the blast.
