TULSA, Oklahoma -- Tulsa Fire investigators say the cause of two Friday morning house fires are undetermined.
Tulsa Fire got the call just after midnight for a fire at the home at Independence and Quebec.
No one was home at the time, but neighbors told firefighters they heard a loud boom inside the home before they saw the fire.
Fire officials say some meth making materials were found in a trash can by the curb, but nothing inside the home. No one was hurt.
And just after 3 a.m. firefighters were dispatched to a home in the 6000 block of West Edison.
When they arrived, they found a home completely engulfed in flames.
Neighbors told Tulsa Fire they saw a camping trailer next to the home leave on Thursday.
The home was destroyed in the fire.
Fire investigators say the home's owners are out of town and they are waiting to talk with them before determining a cause.
Like in the first fire, no one was hurt.
