An early morning fire caused heavy damage at a Gwinnett County home.
Gwinnett Fire spokesman Capt. Tommy Rutledge said four people were in the home — man and wife, their daughter and a friend — and were already outside when firefighters arrived around 2:30 a.m. on the 5600 block of Silk Oak Way near Sugar Hill.
The family heard a loud popping sound, then discovered the fire and called 911.
The interior of the home and its contents were heavily damaged.
The exact cause of the fire is under investigation.
