Firefighters responded to two Tulsa structure fires early Saturday.
The first call was to a home in the 1900 block of North Atlanta Court near Lewis. Firefighters said the home, which appeared to be abandoned, sustained some damage in the 2:30 a.m. fire.
Fire investigators are now trying to determine a cause.
The second fire happened about 45 minutes later in the 3300 block of East Independence.
Firefighters arrived to find a structure behind a home on fire. They were able to knock the fire down quickly.
Again, like in the first fire, fire investigators are trying to determine what sparked the fire.
The fire department says no one was injured in either fire.
